A Cartoon Network.

Gorillaz is the first "virtual hip-hop group," only appearing publicly in animated form. I'm a fan of their music, which has blended the talents of members of Blur, Cibo Mato, and Tom Tom Club.

What I especially like is when Gorillaz is represented alongside other pop icons, like here on Yahoo's home page. It makes "artists" like Black Eyed Peas and Shakira look like the cartoons they really are as well.
