Pretty cool so far. I think it will be really successful with a few more tweaks. Not just because it's a music channel that actually aims to play music (!!!), but also because it introduces the concept of a-website-as-a-tv-channel idea(which I think we'll start to see more of soon). Sort of a natural progression/combination of podcasting, video blogging, and flash video sites.
