When listening to music on my iPod before I go to bed, I usually only listen up to the chorus then switch the song. I guess it's because I want to listen to a whole bunch before I go to sleep, but I don't have the patience to sit there and listen to all of the songs I want to listen to. Speaking of which, when my TV was working, I would listen to music while watching TV. I couldn't hear what was going on in the TV, but I did it so I wouldn't get bored while listening to music. XD
Speaking of music, I usually tend to skip songs before they end because sometimes they take too long to end, so I get impatient.

I'm know I have other weird habits, but I can't think of them at the moment...
