I agree with Richpaca, I used to like them both when they did their earlier stuff! The only slightly newer songs of theirs that I like are Toxic (which is actually pretty old now..) and When You're Gone.
Avril Lavigne
I don't like Britney's newer music very much and while Avril's errr... rebrand was a bit off putting the songs on her new album are pretty decent for self-confessed bubblegum pop
iamthekey; evidently, people do care about them, and if they went off and had slutty lesbian sex people would only care about them more ;)... and ask for tapes.
