Songs won't be played on every station at the same time. According to what is mentioned above, the type of music you hear is generally determined by the station. There are usually several rotations in a specific genre's style of music on most genre-specific stations. To attract new listeners, they may incorporate the occasional rotation of trending songs. Top trending song stations use the same ratings to determine what tunes are popular, which is why they have similar rotations. New songs are added to the trending lists on radio stations as they enter the market, while those that bring in the least profit are removed. Most stations will also consider specific statistics they have gathered from their research, as well as regional and national rankings. The majority of channels will get an understanding of what their listeners like and how often they enjoy hearing the same songs over and over again.
