Well for the most-part some I would say Old-Skool 80's rock is the best music I've ever heard. Bands like Maiden, Metallica Guns N Roses, Motely Crue, Judas Priest, Van Halen and a bit later on stuff like Nirvana. These bands are some of the best music ever. Lyrics which actually mean something, Musicians with actual skill, originality etc. Now adays I find a lack of originality in most thing I hear. Everything from about 1994-2004 was a bit awful. I feel now music is coming back into being good although has reinvented itself as Indie. Bands like Arctic Monkeys, Franz Ferdinand, Kaiser Chiefs, Hard-Fi, The Strokes, The Rakes, The Vines etc. all have an edge about them (Especiialy the first two).
I still hold out hope....
