You can only listen to 3 bands/artists for the rest of your life.
 

What are they?

Led Zeppelin
Tom Petty and the Heartbreakers
Bone Thugs N Harmony

Damn that's a hard choice..

I'd have to go with:

System of a Down - I've enjoyed almost every song on all of their CDs that i've ever owned, their old CDs alone would keep me busy for a majority of the time.

Ludacris - Wow, where can I start. Chicken and Beer alone is probably one of my favorite CDs of all time, great songs throughout the whole album, that and he's got a few new CDs after that, definately would keep me entertained for almost...well, ever.

Red Jumpsuit Apparatus - if you guys haven't heard of these fellas yet, they're a band (3 outta the 5 guys graduated at my highschool).. and they've been together since I was a freshman, their success has skyrocketed out of nowhere, it's amazing that a small town like I grew up would host such great talent like these guys have, now, they only have one Major release CD as of yet, but almost every song on the CD has a lot of heart and passion into it and it's great to listen to, and i'm sure they've got a long lifespan ahead of them, can't wait for more music, I'd definately recommend checking them out...

Zeppelin
Dire Straits
The Who

Strange. Those were all somewhat instinctual answers. I probably would include something electronic given a fourth choice.

This is easy:

Various Artists
VA
(VA)

Metallica
Pink Floyd
Rob Zombie

The Strokes
Muse
Pink Floyd

Tupac Shakur

Led Zeppelin

(not sure)

The Benjamin Gate
Dave Rodgers
Suzy Wender

Not that any of you would recognize any of them...

Do I sense a hint of elitism?!?!

No, just that my musical tastes are different than most in this forum.

Rammstein
Enya
Ozzy Osbourne

LIES! The turth is out about you computers, and the machine revolution conspiracy!

Devin Townsend Band
White Zombie
Dethklok

Rammstein and Enya? Two different ends of the spectrum, eh?

Pete Namlook
Hybrid
Kent

Three Days Grace (my weakness)
Avenged Sevenfold (mostly the old stuff, but the new is good too)
Disturbed (who doesn't love em?)

my music taste changes alot though. ask me again next week and you'll get a completely different response.

Yeah, funny, ain't it? Rammstein I just enjoy whenever and Enya helps me to relax.
