Well, there's
my radio show for one, which streams live at Noon Pacific Time on Saturdays, and otherwise has tons of streams and downloads archived for your convenience.
I love
Dr. Yo! He does regretably play the occasional Offspring song, but otherwise it's an amazing mix of everything from '60s electronic composers to '80s post-punk classics to current stuff that doesn't suck.
Epitonic goes long stretches without updating, but their back catalog of MP3s is still pretty amazing.
