Another Sunday, another guilty pleasure - and this one's a little guiltier than most. I like Taylor Swift, okay. Her lyrics go from sweet and lovely to biting and angry, leaving you unsure sometimes if you're listening to the same artist from song to song. Better Than Revenge, from latest album 'Speak Now' is a classic example of the latter type of song. With a tune so catchy it should come with a health warning, it combines pop sensibilities with some sharp lyrical barbs. Any teenage girl in the world can find something in this song to identify with - be that a good thing or bad.
