An exemplary embodiment will be explained with reference to FIG. 2. In step 2:1 the Application in the M2M network node receives a request for a subscription. The subscription request is a request from the service subscriber to subscribe to the service provided by the Application. The service subscriber could for example an enterprise such as Restaurant, Night Club, Bar or Hotel. The subscriber could also be a person such as a user, an individual, and a consumer, who is for example hosting a party at home. The service subscriber is then assigned a service subscriber identifier, step 2:2. The service subscriber identifier identifies the service subscriber. The service subscriber identifier can for example be a number or tag by which the service subscriber is uniquely identified. There may be several service subscribers that are subscribed to the Application and the Application must be able to uniquely identify each service subscriber. In step 2:3 a M2M music playlist is created. The M2M music playlist is configured to list songs. The M2M music playlist may include a predefined list of songs, alternatively may initially be empty. The M2M music playlist is then associated with a service subscriber identifier, step 2:4. The Application can manage several service subscribers and several M2M music playlists, it is therefore necessary that each music playlist is associated to a service subscriber identifier. The association assure that the Application can always identify which M2M music playlist is linked to which service subscriber.
The service subscriber installs and activates a music player unit so that it is ready for use, step 2:5. The service subscriber may also use an already installed music player unit in the exemplary embodiments. To activate the service of the Application, an activation message is sent from the music player unit to the Application in the M2M network node, step 2:6. The activation message includes a music player identifier. The music player identifier includes information such that the music player unit can be associated with the service subscriber. The music player identifier could for example be a number or tag by which it is possible for the Application to associate the music player to the service subscriber or service subscriber identifier. In step 2:7 the Application associates the music player unit with a service subscriber.
The music player unit scans for mobile devices 100 in the proximity, step 2:8. The music player unit can for example scan the proximity using short range technology such as Bluetooth, NFC or RFID.

In step 2:13 the Application determines the popularity of the songs included in the music playlist received from the music player unit, wherein the popularity is determined based on the occurrence of the songs in the M2M music playlist and the received music playlist. FIG. 4 illustrates an exemplary embodiment. A counter 404 is associated to each song in the M2M music playlist. Further a counter is created for each song in the music playlist received from the mobile device, but the counter is created only if a counter is not already available for that specific song. When the music playlists 401 and 402 are merged into one music playlist 403 the song counter is updated accordingly. Song A has a count of 1 in the M2M music playlist before merging. Song A is also included in the music playlist received from the mobile device. Therefore the song counter for Song A is updated to a count of 2 after the music playlists are merged. Song C is included in the music playlist received from the mobile device but not in the M2M music playlist before the merge. Therefore a song counter is created for Song C. After the merge the song counter for Song C has a count of 1. Song D has a count of 1 before the merge with the music playlist received from the mobile device. Song D is however not present in the received music playlist and therefore the counter remains at a count of 1 also after the music playlists are merged. In the exemplary embodiment of FIG. 4 the occurrence of a song in the M2M music playlist is measured by the song counter. Hence the popularity of a song is obtained from the song counter, the higher the song count is the more popular the song.
The Application sends information to the music player unit about the popularity of a song or songs included in the music playlist, step 2:14. In the exemplary embodiment with reference to FIG. 4, if a song reaches a count of 4 or more the Application send information about that song to music player unit. The Application would send information about songs B, and H, which have a count of 5 and 8, respectively. In an alternative embodiment the Application would determine the most popular song and send information about the most popular song comprised in the merged music playlist to the music player unit. In the exemplary embodiment of FIG. 4, the Application would determine that Song H is the most popular song because the counter for Song H is 8. Information about Song H and information that it is the most popular song is sent to music player unit from the M2M Network Node by the Application. In an alternative embodiment the popularity of several songs are sent to the music player unit. The music player unit plays the songs based on the information received form the Application, step 2:15. The music player unit uses the speaker unit to play-out the songs. If the music player unit receives information that Song B and H have a count of 4 or higher it will play those songs. Alternatively if the music player unit receives information that Song H is the most popular song that it plays Song H.
The music player unit may installed in at Night Club, or in a Restaurant. The music player unit may be a juke box or a DJ mixer that are being used to provide music and songs at a Night Club or Restaurant. The music player unit could also be installed at Home and could for example be a home entertainment system. Once the music player unit is installed, it should activate the service offered by the Application in the M2M network node. The activation of the service may include sending an activation message to the M2M network node such that the Application can initiate the service. The activation message preferably also includes a music player identifier. The music player identifier could be a serial number which uniquely allows the Application to identify the music player unit and thereby also the the service subscriber, which may be the enterprise, the owner, or a user. The music player unit, which may include sensor units, scans the proximity for mobile devices, and this could in the exemplary embodiment be done by a Bluetooth triangulation, where the triangulation is achieved by the music player and the sensor unit, which are positioned at a spatially different location as compared to the music player unit. For example the sensor unit could be positioned at the entrance of the Restaurant, Night Club, or Home, and thereby detects the mobile device such as mobile phones, of the individuals entering the Restaurant, Night Club or Home. The music player unit or sensor units could also scan the proximity using RFID or NFC technology. Once the mobile device is detected, the music playlist is sent from the mobile device to the M2M network node and thereby to the Application. At a crowded Restaurant, or at a busy party at Home, several music playlists will be sent from mobile devices. It may even be so that several playlists are sent from one mobile device. The Application determines the popularity of a song based on the occurrence of the song in the various music playlists received from the mobile devices detected during scanning. If a song is very popular among the individuals visiting the Restaurant or Night Club or a party at Home, it will appear in many of the music playlist received from the mobile devices. The Application will send the information about the popularity of a song or songs to the music player unit. The music player unit will then play the songs based on the determined popularity. The advantage is that only songs that are popular or that at least occurs frequently in the music playlists of the individuals visiting the Restaurant, Night Club or Home will be played.
