YES!

When I think about my primal nature and how I go for the throat when adrenaline is pumping but am tamed and calmed by love, Die Antwoord's Pitbull Terrier is my current song.

Great topic!

Edit: I also really like growling to it :D

Sometimes THIS...

and others...

THIS!

Well, seeing how I just turned fifty, this one seems appropriate:

I Don't Look Good Naked Anymore.

And if you happen to have the misfortune of seeing me naked, this would be the theme song:

It's the End of the World as We Know it (and I feel fine).

Here lately this seems to be my theme.

Unless I really need pumped up, in which case this starts playing in my head until everything lives for the thrill of the fight.

If I get so bad I just need to be so absolutely blinded to the outside world, usually it sounds like this.

My theme song has no words, it's from that scene in Death Rides a Horse when the Mexican bandits play music to the besieged protagonist on the night before the final battle. Little does the protagonist know at this moment that his number one enemy isn't sitting outside...

I don't think I have a theme song but one day when I was walking out of school and taking out my jacket some music started playing and I felt poweful >:D

Call me crazy, but I've always wanted that played at my funeral.

I think the one that best sums up my views on life is from The Offspring.

As of late, this song:

Been fitting my attitude and just how I feel when I am ready to go out and do something.

Is that you singing in the first clip? <3

Edit: I find that first video clip and song hilarious, thank you!

I could have sworn mine was some grand anthem. I hadn't been paying attention for a while. It seems like this is more accurate these days. ;)

My theme song is this.

Not too many songs build up like this one and I love listening to it while skiing or performing some other intensive stuff :)
