at first i want to say that everyday and bounce will be definately #1 at least in austria and in germany cause there are so many fans which buy the album asap- so there will be a big run which means that no other artist will sell an album or a single so many times that he can get in front of everyday or bounce- the question is HOW LONG it will take till they are kicked again and how the other singles will do (no top ten single from crush except iml)

then i wanna say that the songs of britney aren't bad- but i just can't stand the artist and the way of marketing (also the way she sings- although she has improved...) but even desmond child writes for her (and for 1000 others like ricky martin, christina aguilera,...) these songwriters are really good, despite the fact that they make one hit and then they alter the song a bit to make it a new hit (hit me baby one more time/ oops i did it again are technically the same- livin la vida loca and she bangs are quite similar and i think you could put in this row it's my life and everyday- they are not they same but they are arranged quite the same way )
