The last song I had stuck in my head was a celine dion song. Drove me f*cking crazy. It's not so much that the song's stuck, but when you only think on the chorus (that you don't even know the words to cuz you don't listen to celine f*cking dion) and you go weeks with this tune stuck on the tip of your mind. I'm glad it doesn't happen all the time is the best thing I can say. One of my favorite moments on the subject was a friend in a band complaining that he's going to mess up the headliner about writing catchy songs.
Analog's underwear are digital. right now they're set to inverse 1 (I think that means they're on my head).
