I have heard some people talk about music that keeps running through their heads and then have mentioned things I did not really care for.
If you want music that will pop up into your mind at the most inopportune moments just try this one on for size:
It has no redeeming social value that I can think of other than that it is just fun to listen to...
Wait until the next time you are at a funeral or something and "I've got a brand new pair of roller skates" pops up in your mind. It is very distracting.
I have read all sorts of psychobabble on this song and I could care less. It is effective.
