I think anyone that thinks this way is just getting old, I thought Jessie J and Katy Perry were both known for being song writers that had sucess writing for other people at a young age then decided to take a bit of the limelight for themselves? Lady Gaga is a great vocalist, pianist, songwriter and to top it off can dance too. The latest Justin trousersnake song is quite catchy if I remember and he can dance too. I'm not really into that sort of music but people just toss these names into these discussions because their own record collection ended when they left college in 1984, people have said it since the birth of popular music, rubbish, can't tell what they are singing, hair like girls blah blah.
