Truth be told, I was a little underwhelmed with Girl Talk's Feed the Animals, Gregg Gillis' follow-up to the excellent Night Ripper. It's not that Animals was a bad recording, it was just more of the same, as Gillis' short attention mashups were losing their charm and becoming more novelty than anything else.
But thanks to this excellent site, I've rekindled my love for Girl Talk. You can watch (and listen) in realtime, as every single sample is shown as they appear in his songs. You can pinpoint the exact moment where DJ Smurf, The Cure, Usher, and Megadeth all come together at the same time. It's a great way to waste time while at work (as if you were really going to get anything done today).
