That really depends on my mood. Bon Jovi is the only mood-independent band. I could probably spend the whole night telling you what else I like but lately I've been very much in my "Counting Crows" mood. Hard Candy is such an amazing album. I love it.
I also like "Live" a lot. Not all of it. Actually not even half of all but the good songs are sooo good that it's unbelievable.
The list goes on spanning from Elvis (who is still The King and will always be) to Rage against the machine, throwing in some Jazz, Blues and Folk and even Country sometimes but it really depends on my mood.
I'm not really into 80's stuff anymore though. It's fun to hear it sometimes because it reminds me of my teenage years but I got really tired of it.
And I hate pretty much everything that's Pop, Dance or Techno.
