Don't you just hate it when... Watch
I've been listening to Classic fm all week while revising and they've been playing a bit of one of the Brandenberg concertos as an advert and I've been humming it incessantly since friday!
... you get a tune stuck in your head but you only know a couple of bars of it so you just have the same bit going round and round and round and round...... you get the picture! ....
oh god yeah that is annoying. I usually remember lyrics, but just one line. So I go around singing this one line to myself, humming a few bars, then singing the line again.
Best solution is to listen to the song in full... sometimes gets it out of your system.... usually doesn't though!
