So there are basically two main buttons, and these are at the top of each track’s page. These are”Add Pro License to Cart” & “Download MP3 Free”. “Download MP3 Free” – This button gives you an instant download of a high-quality 360kbps MP3 file of the song. Combined with giving a credit, this is the core of what I mean by “free music”. You pay nothing, and can just save this file and use it however you wish. “Add Pro License to Cart” – this adds a license for the song to the cart – fancy that! Once you’ve purchased what you would like, you can now use the song in any way you want, but you no longer have to give credit! See! The Pro License also includes a WAV file of the song. That’s a file format that’s CD quality (or 16 bit at 44.1 KHz).  Some tracks have stems you can do your own mixes (I only include stems this where explicitly stated in the description).
