Check out Seattle's KEXP radio for TONS of new music from every conceivable genre. I've discovered an incredible number of awesome bands via their brilliant youtube channel. Subsequently, I often end up buying the music I hear on KEXP directly from the musicians through their bandcamp.com sites. Paying for music... who would have thought?
KEXP's youtube channel:

Another excellent youtube channel with more of a focus on bluegrass/americana is Liveandbreathing. See here:

And another channel is The Line of Best Fit. It's a UK-based channel offering up a silly amount of great stuff that often hasn't really hit North America yet:

Youtube became the new MTV for me several years ago. SO MUCH great stuff just waiting to be discovered. If you're a music fan, the above will keep you busy for a long time.
And if you're still reading this post, I can't stress enough how much this music has completely changed my life. I was stuck in the 60's/70's for a couple of decades and didn't believe that new music could ever have the same kind of reach and depth as the stuff I loved in high school. Yes, Pink Floyd and Led Zeppelin are amazing bands, but discovering exceptionally talented new indie bands with a different perspective on music writing and creation has opened up a whole new world for me. It's been like going outside on a bright clear day after bring sick and stuck at home for a week.
