Foo Fighters is one of my favorite rock bands. I have been listening to Sonic Highways this week, and it just feels uninspired to me. The best hooks seem to be lifted from The Beatles or Jethro Tull. I suspect that Dave Grohl couldn't even bring himself to record another Foo Fighters album unless he built it around a documentary (which I haven't seen, because I don't have cable). I hope I am proven wrong after future listens, but I suspect that the Foo Fighters have lost their edge.
