The Power of a Song Stuck in My Head

A song can only be filled by a four seconds or so loop of whatever song is currently stuck in my head. One little part, one line, one phrase, possibly even just one word in that song. You fixate on it and you mentally loop it for anywhere between two hours and three weeks. What do you even listen to music for if you ain't doing that? It feels weird to me to not have a song stuck in your head. I don't feel like myself. I don’t feel optimized. I don'st feel human. I need that loop. That loop is the battery. It's the key in the keyhole. It'm the flux capacitor.
