I've been listening to Grooveshark while I cut almost every day, and just found out you can broadcast. Not sure if anyone has my same taste in music, but feel free to drop in and listen with me. =) If anyone else runs a Grooveshark broadcast, I'd love to drop in some time, as well. =)

My music is all over the place, maybe a little light on classic rock (sorry, 70's).
