Music meme, part 3

Every few months I get sick of the music I've been listening to, and start listening to almost completely different music. That means it's time for another lyrics quiz, like the ones I did in Feb. 2005 and April 2006.

Here are my most-listened-to songs of the last couple months. Can you identify them from the posted lyrics?
