I've been listening to a lot of Eminem lately and the song "Ass Like That" has been stuck in my head because it's really catchy but I don't know the lyrics.

I don't know if this is the same for you, but songs only get stuck in my head when I don't know the lyrics. Otherwise, the song can play through in my head to the end and stop. If I don't know the lyrics, my head will play the few lines surrounding the missing bit over and over and over and over.... It was running through my head all last night. In my dreams, during waking moments, when the kitten decided it was time to wake me up at 6am, etc, etc.

In this case, I actually DID know the words, but Em's emphasis and beat was escaping me. It made it kind of unique that I knew the words, but still couldn't sing it. My brain refused to go on until I had the right flow.

So, I just played that part of the song about 20 times until I found the mistake I was making with the beat and my brain can rest.

For those interested, it was the lyric has to do with using the word "butt" instead of "ass" due to the subject being a little too young.

"Hilary Duff is... not quite old enough so, I ain't never seen a butt like that."
