I was thinking the Stereo Love by Edward Maya and Vika Jigulina.
And I'm not going to judge you for liking that Vanessa Carlton song. I too enjoy that one, and a couple of Michelle Branch songs (especially when she's with Santana). I do also like Ke$ha and Lady Gaga, but I think it has a lot to do with how easy and slutty they are.
I can't help you on Bieber or Swift though. I don't have a single song from either on my ipod. Kanye West was right though, Taylor Swift did not deserve that award, and Beyonce really did have one of the best videos of all time.
