I've been looking for a show to listen to for some time that has some decent music in it. Finally I've found one:
The podshow music rewind: http://rewind.podshow.com/
Check it out. This guy plays clips from all the podshows, showcasing the best new music from the podsafe music network.
I came across it thanks to Adam Curry http://curry.com/
Fyi: you can subscribe with:
Juice (desiigned for the job) http://juicereceiver.sourceforge.net/index.php
or bashpodder (quick & effective linux script) http://linc.homeunix.org:8080/scripts/bashpodder/ - my favourite
there's many more of course.
