How many songs do radio stations actually have?

Question

like how many songs in a music library do radio stations have?

Answer 1

Not really sure but it seems that they only have like the 10 most popular songs out and play them over and over and over...Did you ever call the radio station and ask them to play a great rock song...I mean an awsome classic from say five years ago and they say sorry can't do that...bugs the h**l outta me
