A++ All of these songs are songs that could change the world. Play any of these songs in a difficult situation, and the situation will all of a sudden get done.
I have owned up to liking an Ashlee Simpson track in the past, i.e. "Boyfriend", but that one is just terrible.
But the rest here - is outstanding.
Taylor Swift is terrific, and so is that Oasis track (the album they did release this year I love as well). Also great to see Coldplay, Metallica, Pink, Raconteurs, and freakin' Paramore.
