I'm not sure if it is because of streaming. But since I rarely turn on the radio, I only use YouTube, Spotify, and Pandora to discover new music.
Something I've noticed is that there are artists that are always in the media, but you can spend a whole day at the mall and not hear a single one of thier songs. For example, Kendrick Lamar... super famous, but I can spend a whole day outside and not a single car driving by is playing him. However walk into someplace as simple as Walgreens and thier playing Escapade. Why do you think this is?
