Seconding Adele being over-rated. Her music is beautiful as is her voice, really. But she isn't god. Her new song isn't very good, and even some of her stuff on 21 isn't that good.
Radios need to play what's good as opposed to what's just popular. (This is more of a generalization, really.)
50s/60s musics are the best musics.
Neon Bible is a terrible album, and The Suburbs was way better.
Coldplay is excellent, but over-rated.
Florence + the Machine is one of the greatest songwriters of our time.
Bjork's music really isn't that weird, and if you can't handle it, you seriously need to expand your music tastes.
