Radio doesn't look for any songs.They have continuous things submitted to them by every solo artist, every label, every manager, imaginable. They play songs from artists who are touring and in the public eye. Those artists are promoted by advertising purchased by their companies, or the aforementioned managers, labels. If you are not one of those artists currently performing in regional areas, don't look for anything to ever be played outside of small niche markets, some college stations (who really just play college acts) or independent podcasting or web based stations.

Music is always a one on one experience with performers and audiences. That never changes.
