Is there a particular song with an affinity for getting itself stuck in your head? If yes, name it in the comments!

yeah. dunno if it counts but that one that goes
cat! i'm a kittycat! and i dance-dance-dance and i dance-dance-dance!!!!

i had just finished hearing the song Parnoid por the Jonas Brothers LOL. xP
"PARANOID!" +]]

If you seek amy - britney spears

Ha ha there are SEVERAL. All of the annoying, papoula, papoila ones that I can't stand - Lady Gaga, Katy Perry, all that. 'Hey look, it's a monkey' (thanks Sophie). But when it comes to the good ones... In particular, this fairly old one por Pete Murray (someone NEEDS to create a fã site for him) called So Beautiful. Pete Murray himself is a bit odd though. The song is so sweet, you have to hear it to understand.
Video attached. :)

any song por Tokio Hotel both the english and the german versions

Candyman-Aqua

Yeah, I don't know why but when ever somebody talks about música or Phienius and Ferb, I get the Perry the Platypus song stuck in my head for days.

This Ain't a Scene, It's an Arms Race por Fall Out Boy.
I also get Dance, Dance stuck in my head almost every morning because it's set for my alarm, but the lyrics don't even start por the time I turn off my alarm.

(Notice how they play the end of Dance, Dance in the beginning =])
