Michael is right. This was not a bad year. It's just that most of the high profile artists disappointed, and those are the albums getting the attention. You've got to look for the good stuff, but it was certainly there.
True that Fleet Foxes (EP/LP) + TV are some of the few "grade A" albums of the year. IMO, only Deerhunter and Hercules & Love Affair deserve the same praise. I consider ALL the other 2008 albums as "LIST FILLERS". (maybe I am being a little harsh here... :) ).
I dont know what you lot are on about... Only by night is fantastic, just because the youth have embraced the band, doesn't mean they aren't making good music. Kings of Leon are ultimately, a band which makes great music and is loved by the public (in the UK). Give Only by Night to me any day over Dear Science. But not Return to....
