In no particular order and not really as a rule but for the moment:
Killing Joke
Tool
White/Rob Zombie
Nine Inch Nails (a lot of the lyrics are shit, but the instrumentals are actually good)
Queen
Incubus
Thin Lizzy
Primus
The Offspring
Queens of the Stone Age
Honestly, I like a lot of bands and a lot of music, these were the first to come to my mind when I thought about it, though.
I'm certainly not a traditionalist, but I think it's harder to find good music these days. It's still made, it's just not what's most popular, in my opinion.
Same with rap, actually. I listen to some hip-hop, but pretty much nothing that is every played on the radio.
