Let the music move you

I was woken up just after 5:30am {EST} by the urge to hear this song.    Anti-Hero Man   by the Kings. 
So here's me, running around the apartment like a piece of crazy trying to find my cassette - yes it's that old- of mixed stuff from the 70's and 80's with this song on it.  Then I find it, and realize it's 5:45am and way too early to be playing music in the apartment.  And of course I do not have earphones that fit the old stereo.

Why is it that certain songs jump into your brain and you can not stop thinking about it until you've played it a few times?

That is the thing today I just have to wonder...
