Thats a tough one....depends on the situation....but for the most part I listen to ....
Creedence Clearwater Revival (Live concert album)
Alice in Chains (Best of the Box CD)
Rob Zombie (Hellbilly Deluxe)
Metallica (Black album)
Seether
Rolling Stones (Forty Licks compilation.....not to bad)
Days of the New
Patton (soundtrack...for those special GV missions)
The Doors
Aerosmith
Starship Troopers (soundtrack...yellin' BUGS!!!!)
Top Gun (soundtrack....LMAO, imagine THAT one

)
thats the major bit, also like a dash of Beethoven as well, completes the mood.
