I'll go through the decades of music I know, and suggest why I like them. I do really like most music, so...
1950s - Rock'n'Roll, at its grassroots, and blues also. Damn straight, white boy.
1960s - A close second in terms of my favourite era, because of the Beatles and the Rolling Stones. I'd say 1962-66 were my favourite years here, because of the God that is BOB DYLAN. Bow before him. Now. Also, there was that Hendrix guy, and Cream/Clapton.
1970s - You had Zeppelin, you had Sabbath, and later you had punk and stuff... but not in the charts. You look back and think "ooh, heavy metal and punk, cool!" but actually it was all disco and ABBA. The only punk bands who got into the charts, for real, were the Pistols and the unsung heroes - the Boomtown Rats.
1980s - People say that it wasn't good, and they have a point - Guns'n'Roses? Bleugh. The beginning of hip hop? Ugh. The start of dance music, Satan's synthesiser-tunes? Kill me now. But in Britain, where proper music is made, we the single greatest band ever, bar none - The Smiths. VIVA MORRISSEY!
1990s - I like Nirvana as much as the next person, but they were the only grunge band that didn't deserve to be shot in the mouth - how ironic. Oooh, I tagged Cobain, wait'll the Americans get all angsty on me. All other grunge was bad. Period. There were three good Britpop bands - Oasis, Blur, and Mansun. That is all.
2000s - I fear this decade will become famous for shit dance music and even worse R&B, but just outside of the top 5 in the UK we have some of the best music since the 80s going on - Franz Ferdinand, the Libertines (not anymore, alas), the Killers, and for once the Americans making good music in QOTSA, Bright Eyes, Beck, and the like. This decade also has Patrick Wolf, who I love to bits. He's great, if anybody else has heard of him do say, because I don't know any other fans.
Music is my passion, I love it. I'm also very opinionated about it, sorry if I offend anybody. But, come on, grunge was utter fucking bullshit.
RK!
