all i know is i got 800 songs ranging from Sinatra, to the Stones, to Pearl Jam to Ray Charles to Flo Rida on my IPhone on shuffle every day at work and in the car. I never know what song is coming on ! haha. I haven't listened to the radio in 3 yrs. https://www.spotify.com/us/
What's funny is that half of the Gen-Xers and (probably) none of the millenials have a clue what that post is about.
