The "Adult Swim" theme on Cartoon Network

What is that song? Who performs it? Why is it familiar to me? I’ve heard it on various other channels for various other shows (including TLC) so now I’m really curious. Does anybody know?

It’s familiar because it’s been used as stock music for various commercials. It was used on a HotJobs commercial and in the first episode of the Osbournes. From what I’ve read, it’s a remix of an old Tito Puente tune called “Mambo Gallego” by Blue Tube. Hard to find too, I hear.
