"Power Song"s

So I have an iPod Nano (old school, I know) and it has the ability to set a "Power Song" when you are working out. I think of it as a song you choose to help you when you're struggling during your work out. I'm just curious (and looking for new music recommendations) as to what many of you would choose to be your "Power Song"? Like if you had to pick 3-5 artists and 1-3 of their songs? Any and all music recommendations are welcome!

Here are a few of mine:

Halestorm: "I Miss the Misery", "Love Bites (So Do I)", "Mayhem"

Nirvana: "You Know You're Right", "Come As You Are", "Lithium"

Garth Brooks: "Ain't Goin' Down (Til the Sun Comes Up)", "The Fever"

Ritchie Valens: "La Bamba"

P!nk: "Blow Me (One Last Kiss)", "U + UR Hand", "Beautiful Trauma"

There's a weird assortment of music for ya. (Just a note if you are interested in any of these songs, some of them are explicit).
