I like to rock out during my workout.

Tool
- Parabola
- The pot
- Lateralus
- Jambi
- etc...

Metallica
- Stone cold crazy (so good...)
- Breadfan
- master of puppets
- many more...

Nirvana
- Breed
- Smells like teen spirit
- in bloom
- stay away

Pearl Jam - Animal (live)
Rush - Working man (live..this song fuckin rips)

Led Zeppelin (live stuff...how the west was won is a great album)
- Bring it on home
- Heartbreaker
- The ocean

God, there's so many others. Gets me jacked up just thinking about it. I like live music for working out. Bands usually put so much more in to it and it's always faster than studio versions.
