70s rule! Age of awesome rock and classic heavy metal! It was a very varied decade but as I'm a rock&metal fan I'll concentrate on that a bit. I love many many bands that are not mentioned here (like Jethro Tull, Led Zeppelin, The Who (they had awesome 70s albums), Genesis with Peter Gabriel, Rainbow etc etc. The 70s took the foundations laid in the 60s and made one breakthrouh after another. I like to think of it as a decade of experimentation without rules. Still, the rocking parts were the best .

The 60s were awesome as well but most of the 60s bands I love had some of their best stuff released in the 70s, so...

The 80s had some cool metal...I just didn't like the direction many pop artists took. The 90s were cool as well but I only really like a handful of bands. I never had contact with the good 90s stuff as a child because most people listened to europop/boygroups etc at the time. I never lliked that garbage and heard some classical music instead.

Looking back I can listen to the "garbage" again with nostalgia, actually but it's more fun than anything. I have yet to find (popular) music (edit

or metal after 2000 that I really llike, apart from a few exceptions, of course.
