I saw an article just now about MTV's new music site mtvmusic.com which I didn't realize was live. I saw the MTV Content API they released a while ago, but I didn't realize there was a video site to go with it.
20,000+ music videos! Pretty awesome. Everything from Rick Astley to naked Britney to some seriously old stuff like the Styx Mr. Roboto video I embedded above (which I didn't know existed!).
Man, this is almost as good, maybe even better than Songza!
