Help me, Obi-Flist-Kenobi, you're my only hope

I need fast-paced songs to walk to that have no lyrics, have fairly incomprehensible lyrics, or have lyrics in a foreign language that I will not be tempted to start singing to as I walk in the early morning. (Humming, unfortunately, will continue to be a risk, but that's my problem.) Preferably songs that evoke some kind of bad-assery, as in "Why yes, I DO know how to use this," or "Are you sure you want to try to take over the world while I'm still alive?" or "In fact, I AM the sexiest person in the universe."

I have a few songs like this in a playlist already, but I find myself needing more... any suggestions?
