I can deal with having a song stuck in my head. It's annoying, but whatever, it happens all the time.
I can even deal with having my own song stuck in my head. It's more annoying, but it's an occupational hazard for being a composer. I talked about it in Chapter 10 of Orchestra of One... I can totally deal with it.
But the song stuck in my head right now? It's the worst.
I've been composing a song for the last few days, and have been making revisions and changes to it. And it's an old version of the song that's stuck in my head. A version that NO ONE ELSE WILL EVER HEAR.
AAAAAAAAAARGH.
