Anyone use any other streaming music site similar to Pandora? Our proxy at work is blocking it now and Im getting tired of listening to ktar online

I used to use launch.com but thought pandora did a better job is playing music I liked

So just an update to what Ive found

jango.com
jiwa.fm
last.fm
grooveshark.com
