How 'come no one tells me these things?  I just found out that MTV just launched a music site at the end of October that puts a ton of their music videos online.  This includes traditional music videos, concert footage (including "unplugged" sessions), and interviews with the artists.

The selection is good, but not great.  I couldn't find material from a bunch of smaller artists.  But it's still handy since I never watch music videos on TV.

Check it out at www.mtvmusic.com

They also allow you to embed the videos - here are a few songs I like:
