1) When this shizzy happens, I usually belt out the song...over...and over...and over.
2) It's bits and pieces of the Big Time Rush soundtrack. I blame my friends for having me go and take them to the concert and record it for them earlier this month (they know who they are).
3) Right now, I can't. I attempt to get rid of it by trying to sing songs by a different artist, but nope, Big Time Rush is still on the brain!
