When I was younger it was Pandora. I'd listen to Pandora channels and if I heard something new I'd grab the artists discography off limewire. Go through and see what I liked. Sometimes I'd see who opened live for the artists I really liked then listen to them too. Now that I can afford to support artists I try to by buying physical media. I swap it with friends. I have 3 buddies I do this with. Every month or so we trade an album or two.
