Inside fish sticks, outside tartar sauce. Pocket full of celery, imagine what she tellin' me.

Songs new to last week's Billboard Top 50 singles chart, and the top debut.

#31 (from #76): Pussycat Dolls, "When I Grow Up"
Wouldn't this declaration of ambition be more appropriate on someone's first album? Wouldn't it have made more sense for the vocal hook to be "meow meow meow meow?" (the non-Nicoles being pussycats, you know?) Neither change would actually make the song any good, but it would show a little more thought on the part of its creators.

#36 (debut): Young Jeezy feat. Kanye West, "Put On"
I won't tolerate Young Jeezy for allegedly being the best unimaginative hernia sufferer in rap, but it's charming when he briefly drops food metaphors I don't entirely grasp. Kanye does not improve the song by pondering fame through a vocoder.

#49 (from #56): David Banner feat. Chris Brown and Yung Joc, "Get Like Me"
Despite the failure of last year's "Speaker," David Banner would like you to know that he's doing nicely (the proud owner of a several cars), and that he can still get people like Chris Brown and Yung Joc to appear on a status report.

#50 (from #62): Three 6 Mafia feat. Project Pat, "Lolli Lolli (Pop That Body)"
It's a little odd to hear Three 6 Mafia pretending to be Flo-Rida feat. T-Pain, but "like Barack Obama said, yeah, it's time for a change!"
