I Write the Songs That Make the Young Girls Cry

[shanmonster]

I have an excerpt from a rock song in my head that goes something like this:

You build me up
You put me down.
You're nothing but a waste of time for me.

Here's what I want to know: is this is a real song, or is it something I made up in my own head? Either way, it's not a very good song, and the melody sucks. The latter is why I suspect I made it up. I'm terrible at music composition.
