Out sick; Need your help

I missed Lincoln Calling. I missed Local Natives. I missed Little Brazil's "comeback." I missed Cursive. I missed Land of Talk. Lately, I've missed a ton of stuff.

Basically, I've been sick for about a month, which has required multiple doctor's visits, blah blah blah. You don't need to know the details. Anyway, you probably haven't seen me around lately. And I haven't seen the inside of a rock club since August.

I also haven't seen the inside of a gym in more than a month. Barely being able to breathe isn't exactly conducive to working out, you know?

I was readying myself for the gym this morning and realized I hate all of my old "working out" playlists. They're old, uninspiring.

So, I'm making some new ones. But it's been tough. You gotta follow the rules for a good playlist, but on a workout playlist it also has to be music that pushes you through that last rep or drives you through another mile.

That's where I'm stuck.

I have the following on my list so far:
"Slack Motherfucker" by Superchunk
"Slight Figure of Speech" by the Avett Brothers
"Tell Em" by Sleigh Bells
"Percussion Gun" by White Rabbits
"The Seeker" by The Who
"You're the Best Around" by Joe Esposito (yes, the song from the montage scene in "The Karate Kid")
"Cyanide" by Metallica
"Burial" by Miike Snow

But they aren't final choices by any means. I need more. I need better.

So, what do you think? What would you suggest for the perfect workout playlist? What's on your list? What's the best workout song ever? (Aside from "Gonna Fly Now" from Rocky, that is.)

Let's talk in the comments.
