Hah, excellent... sometimes if I feel like I've been too lazy and should go to the gym I'll just chuck that song on, then afterwards I'm good to go.
Some good stuff mentioned on this page like GYBE, Borknagar's s/t, Agalloch, Asunder, etc.
Not listening to anything right now, but the last CD I chucked on was AC/DC - Let There Be Rock. Surely these guys have gotta be close to retirement, but I'm gonna cry if I don't see them live before they do.
