I've played pretty close attention to the playlists. I really liked some of the other playlists, but this one seems a bit forced and not as strong.
For previous lists, I felt like it was entirely possible that some of those songs could actually have been the origin of some of the ideas in the books, or some of them could have rounded out ideas Stephenie incorporated in her books. But I find it very unlikely that she was listening to the beach Boys or Simon and Garfunkel while writing Breaking Dawn.
Maybe that sounds too nitpicky, but it's the best explanation I can find for why this list doesn't seem as well-put-together as past playlists.
There are some bright points (My Never, Death Cab, Muse), but overall, I'm disappointed.
