Well it usually doesn't work out and/or it's usually not good.
I don't like Lindsay Lohan so I'm against that, definately.
Paris Hilton, we'll she's a celebrity for being rich so she might as well try to apply herself to something that makes her deserving of the attention that she recieves. Though she doesn't really seem to interested in the album, it seems like a tool to get more attention and money, neither of which she needs.
I think Hilary Duff has a good voice, and her songs don't bother me really. Maybe that's because I've met her and I think she's really nice.

Ashlee Simpson kind of annoys me because of the show and all, I don't agree with how she's recieving publicity - through her sister and a reality show she wouldn't have if it weren't for her sister. The recording of pieces of me sounds good, but when she was rehearsing it on her show (which I've only seen once, I swear) she sounded really bad singing it, so I dunno how much of that is her and how much of that is digitally enchanced and stuff.
JLo - I don't like her songs, didn't care for her as an actress (save for in Selena), and I don't think she deserves the attention that she gets. I heard she's quite a diva too.
