And they have a pretty slick animated TV ad running, with the Napster cat character going to a party and jumping in the pool at the end.

It was amusing seeing that particular ad running during the South Park episode where the FBI busts Stan/Kyle/Kenny for illegal song downloading. What a hilarious segment:

"That's Britney Spears getting into her private jet. Notice anything wrong?"
"No."
"That's a Gulfstream 3. Because of illegal song downloading, she had to sell the Gulfstream 4. The Gulfstream 3 doesn't even have a remote control for its surround sound DVD system. Now do you still say that downloading music is no big deal?"
