Taylor Swift - 22

As good as Taylor Swift's latest album Red is, there is still one song that shines a cut above the rest. The joys and frustrations of being 22 years old is perfectly described in what is a killer dance pop song: "Yeah, we're happy, free, confused and lonely at the same time, it's miserable and magical, oh yeah." Co-written and produced by super-producers Max Martin and Shellback, it's one of those songs that make it hard to imagine Taylor Swift ever being a country singer. Then again, who cares?
