These two songs, and "Breath" are 3 of my favorite cardio songs. Never liked "Firestarter" much, even though it was their breakout and got me interested enough to check them out. They were just so different for MTV, that it got overplayed IMO.....ruined it for me.

"Smack My Bitch Up" has an awesome NSFW vid....only aired on MTV a couple of times after midnight, but I don't have a YT account so even if I found it I couldn't watch it to make sure it was the right one to post here.
"Narayan" is so cool to listen to when you know you're hitting a wall doing cardio The beginning the lyrics push you, and at around 4:15 I'll just go backwards on the elliptical once it slows for a bit, and just take it easy the rest of the song....it's like doing yoga and cardio at the same time.

Then I'll play to "Breath" followed by "Smack My Bitch Up", and then a few Lords of Acid songs when I'm in the mood for that type of music. Cardio is a breeze on those days.
RIP Keith! You were probably a weird dude, but your music helped me get through the part of working out I hate!

Is falling down on everyone
You're breaking free and the morning's come
If you would know, your time has come
If you believe the western sun
Is falling down on everyone
And you feel it burn, not try to run
And you feel it burn, your time has come
I feel it...
I feel another energy
I feel a power growing
I feel another energy
I feel a power growing
I feel another energy
I feel a power growing...."
