The entire Rage For Order album by Queensryche is my favorite to workout/jog to but most 80's metal/rock will do it for me.

I don't have a playlist made yet, but I keep skipping to the same things... (while wishing I were fit enough to be running!) They are:

Dedmau5 - 8bit, Some Chords, Raise Your Weapon, One Trick Pony, Ghosts 'n' Stuff, Hi Friend!

Jay-Z - 99 Problems, Public Service Announcement
Ladytron - Deep Blue

I'll add more if I think of any :)

I don't have a workout playlist yet, but just let me say that I am so happy to see that there are still people in this world with good taste in music!!! Thanks to you all, I do have some new artists to check out though :)

This is my Power Song. It's the best mash-up ever:

"Smells like bootylicious" by 2ManyDj's. I'm sure you can guess what two songs they uses.

It gives me instant energy, haha. :-)

In This Moment
Halestorm
P!nk
Lady Gaga

Has anyone listened to the new Fall Out Boy album yet? It has so many songs that have that anthemic feel to them, you feel like you're listening to your own bad *** movie soundtrack while working out to them.

A few other songs I love running to:
Whipped Cream-Ludo
The Tears-Robots In Disguise
Men In Love-Gossip
Dressed to Kill-Sharon Needles
[edit]OH AND someone on Tumblr made this incredible mashup where they put Head Like a Whole over the tune of Call me Maybe. SO GOOD.

New album? Gunna have to check that out for sure!!!

I don't have a specific playlist, just stuff I like to hear.

For warmup, I like to listen to EDM. I'm really into Tiesto and Armin van Buren.

When I'm into my cardio, I like Punjab bangra music. You cannot NOT smile while listening to Daler Mendhi! It's very danceable and happy.

For lifting, I listen to my Finntroll, Korpiklaani, Cradle of Filth, Marylin Manson.

I like something that still rocks, but on the mellower side, as I wind down. H.I.M., Sirenia, Tyr, Lynyrd Skynyrd, Zeppelin.

Yes, I do love Scandinavian music. It's where all the best modern metal is coming from right now.

Seriously been getting extra energy from Lady Gaga's "Applause". It's so powerful and makes me want to go longer and faster on the elliptical.

I've got a huuuge run playlist, but there are a few songs on there that when they come on, suddenly my legs aren't feeling tired at all anymore, and I get a fresh burst of energy

In no particular order,
Animal by Conor Maynard
My Songs Know What You Did In the Dark (Light Em Up) by Fallout Boy
Teeth by Lady Gaga
Closet Freak by Miss Lawrence
Starships by Nicki Minaj
No One Lives Forever by Oingo Boingo
Dead Man's Party by Oingo Boingo
Don't Stop Me Now by Queen
