This is how I used to discover music when I was a teen: I would listen to the radio and hear a song I'd never heard before and that I really dug. I'd wait for the DJ to tell me the song title and artist, or I'd go on the station's website to see what their current rotation was and try to determine it from there. Then I'd download the song and a few more from the artist on Limewire, and if I liked enough of their music, I'd go to a shop and buy their CD.
