Lyrics and the Brain

So as I sit here programming a couple web pages, ok learning to program some web pages, something just dawned on me. There is a great deal of my brain filled up with song lyrics, particularly songs from the 80's. It doesn't matter what genre of music, I just seem to know the lyrics to way too many 80's tunes.

Or course I have brought this on myself this evening as I am currently listening to said 80's music. But honestly, how much of our brains are filled with lyrics to random music. Stuff that you don't realize that you remember but as soon as the song is going you are singing right along with it.

Case in point....

Thinking of a master plan
This ain't nothing but sweat inside my hand
So I dig into my pocket all my money's spent
So I dig deeper but still comin up nothin but lent
So I start my mission leave my residence
Thinking how could I get some dead president's
