Let me see...stuff that I like to listen to:

When I just want to chill:

"Room For Squares"-John Mayer,
"Live in Europe '72"-Grateful Dead,
"Live at Red Rocks"-Dave Matthews Band;
Greatest Hits of Tom Petty & the Heartbreakers,
"Endtroducing"-DJ Shadow
"Kind of Blue" Miles Davis
"Head Hunters" Herbie Hancock

When I definitely do NOT want to chill:

"Back in Black" AC/DC
"Use Your Illusion v.1" Guns N Roses
"1984" Van Halen (Panama probably should only be listened to in a 1983 Porsche 911 Targa in Porsche (Guards) red, in all fairness. Nothing else seems right!)
"Ready to Die" Notorious B.I.G.
"The Chronic: 2001" Dr. Dre
"Southernplayalisticadillacfunkymusic" Outkast

When I'm rolling with friends:

"Ten" Pearl Jam
"Vitalogy" Pearl Jam
"Aquemini" Outkast
"Devil Without A Cause" Kid Rock
"August and Everything After" Counting Crows
"Blazing Arrow" Blackalicious

For driving HELLA fast:

"The Bends" Radiohead (I don't know why, but it always comes on when I drive fast)
"I Get Wet" Andrew W.K.
"Frampton Comes Alive" Peter Frampton (We hit triple digits on our way to Canada in my friend's mom's Mercury Villager while listening to this)
"Veni Vedi Vicious" The Hives
"Toys in the Attic" Aerosmith
"Temple of the Dog" Temple of the Dog (members of Soundgarden and what would become Pearl Jam, in case you aren't up on your Seattle grunge-rock history).

These are only a few of my favorite albums, but sum up my taste pretty well
