What are your favorite workout songs?

Guys, I don't want to be indelicate, but...

My ass hurts.

Oh my god, does my ass hurt.

I went to spinning last night.  Because I'm a glutton for punishment.  Spinning was hard.  At first, I had a hard time standing up on the bike during the "stand up and push!" portions.  But halfway through the class, my bottom was BEGGING me to stand up.  And this morning I feel like...  well, there's no simile that describes how my butt feels that isn't obscene, so suffice to say that I hurt.  And I hurt all the way through bootcamp this morning.

Owie.

So let's talk about something other than my butt, but still related to exercise:  music.  I work out at two different gyms - there's one close to my house, but older, and one a little further away and newer.  The newer one has personal TVs on most of the equipment, and I really enjoy doing an hour on the elliptical while watching Paula Deen's show on Food Network (oh, the irony).  But when I'm at the older gym, I tend to listen to music on my iPhone.  I have a few very favorite songs to work out to:

1.  Bad Romance, Lady Gaga - This song alwaysalwaysalways gets me going from the very first notes.  It's got a great beat and helps me to set my pace with whatever I'm doing.
2.  Bouncing Off Clouds, Tori Amos - I'm a huge Tori Amos fan (I've seen her in concert at least half a dozen times) and I love how this song couples a fast beat with such sad lyrics.  I don't always want to work out to shinyhappymusic, you know?
3.  Get Some, Lykke Li - You may recognize this song from a Lexus commercial.  I love this whole album, but this song is really fun and empowering.
4.  Hard, Rihanna - Whenever I need to power through something (like the last five minutes of a really intense workout session) this is what I put on.
5.  In My Pocket, Mandy Moore - What can I say - they can't all be Serious Songs.  This is a total guilty pleasure! 
6.  Karma, Alicia Keys - This song is neither too slow nor too intense - it's like the goldilocks of workout songs.
7.  Mean, Taylor Swift - I'd like to dedicate this to all of the jerks who made fun of me in 6th grade.  I rule, you drool.
8.  Part of Me, Katy Perry - Almost against my will, I think you have to have a Katy Perry song or two on your workout playlist, right?
9.  Teenage Hustling, Tori Amos - I love any song that contains the word "skankin'."  How can you not?
10.  Love Is Blindness, Jack White -  This is a cover of one of my favorite U2 songs.  My love for U2 cannot be understated - I've seen them in concert 5 times in four different states.  But this version has such a nasty, dirty vibe to it and a great beat that makes it ideal for working out.

So those are my favorite workout tunes.  What are some of yours?
