I used to listen to Led Zepplin a lot, then I listened to older rock & roll, blues, and jazz and it got to a point where I couldn't listen to Led Zepplin anymore, I'd hear something like Whole Lotta Love and have to think to my self "damn...that sounds like they just ripped it off of such-and-such tin pan alley band".
That's why I don't listen to most older rock/metal-ish stuff, I can't listen to it and not think about how white culture has taken so much from black culture only to give back so little.
If you need me, I'll be listening to Straight-Edge, Hardcore, Punk, Indie, and "DC Emo". If you want to rip on the emo part, let me clarify this - emo to me is Mineral, Rights of Spring, Lifetime, Texas is The Reason, Fugazi, Sunny Day Real Estate, Cap'n Jazz, etc. (mostly defunkt 90's bands) It's not My Chemical Romance, Fall out Boy, Hawthorne Heights, etc. Those are alternative rock, post-hardcore, and "pop punk" whatever the hell that means.
P.S. I'm not Caucasian so don't let this offend you if you are and happen to listen to music that was taken from black culture.
I leave you with the lyrics of this song by Minor Threat, a great band. The song is "Guilty of Being White", you've probably heard the cover of it by Slayer that goes "Guilty of Being Right".
It's an anti-racism song, although it might seem the opposite. Ian MacKaye wrote the song when he was a minority at his high school of 70% blacks and he was sick of being picked on for being white and a minority.
I'm sorry
For something I didn't do
Lynched somebody
But I don't know who
You blame me for slavery
A hundred years before I was born
Guilty of being white
I'm a convict
Of a racist crime
I've only served
19 years of my time
Guilty of being white
