I've got Marissa Stole the Precious Thing stuck in my head right now!!!
What song is stuck in your head?

Common ones recently:
Boneyards by Parkway Drive
Yellow Wings by Keepaway

Explain that.

It's called "Marisa Stole the Precious Thing".

I've had Disturbed - Land of Confusion stuck in my head for over a week.

I have the Tetris theme (Korobeniki) stuck in my head, as well as the Godfather Theme, Beethoven's Symphony No. 7, and Baba Yetu from Civilization 4

Lady Gaga, Bad Romance and Poker Face... sort of

We keep bringing them up / playing them at work

Curse you, iPod Touch spellcheck!!!

Time is running out - Muse

I've had a whole array of songs from You're A Good Man Charlie Brown stuck in my head. I'm in that musical.

Thick As A Brick - Jethro Tull

Brand New Day-Dr. Horrible's Sing Along Blog

I'm listening to that song right now. By random.

I love that song... I bought it on Amazon's mp3 store and burned it to CD but while singing along I realized something went awry either with the burn or the CD got scratched and there are three or four segments within it where it skips 1/2 -> 1 second worth of the song. Drives me crazy =(

Nothing stuck in my head, but I've been listening to Godsmack - I ****ing Hate You and the rest of the album Faceless a lot lately.

And now Simon & Garfunkel's Sound of Silence (thanks to the Favorite Song Lyrics thread I ran across this morning).

Hot Air Balloon - Owl City
Replay - Iyaz (I dislike the lyrics of this song, but the tune is okay)

My roommate would love you.

Rhinestone Eyes

• Gorillaz

Mega Ran - Splash Woman

I get it stuck in my head all the time, of course this is the case with most 8-bit Mega Man music.

Nice one, I just listened to that recently.

I love my computer - Bad Religion

Guns N' Roses - Sweet Child O' Mine
Lady Gaga - Paparazzi

You should check out his website he put out a new song inspired by MM10.

LOL. Never gonna give you up, Chocolate Rain Etc.

I've been listening to The Flying Lizards' cover of Money all day. Their other music is just as good, if not better. And it looks like their self-titled LP is going to be rereleased on CD in a couple weeks.
