LOL, there is another song going around that also samples "Na Na Hey Hey." It's called "Goodbye" or something by Kristina DeBarge. And it sucks. But I've been wondering whether she's related to the DeBarge family (musical family).
Ah, here she is... She's incredibly hot.
Kristinia DeBarge. Rumored to be the secret daughter of James DeBarge and Janet Jackson 
I've heard this song on the radio 3 times in the last 2 days.
