I'll also say that radio's not quite dead yet -- you just have to look to the noncommercial, left-end-of-the-dial.

I've found a remarkable amount of "new" music by listening to Austin's NPR affiliate, KUT -- especially the morning show Eklektikos, which airs from 9am-1pm CT. (Their website offers streams if you'd like to check it out; click the "Listen" tab.)
