A game with songs that get EASILY STUCKIN MY HEAD!!!!
I played Super Mario World, and when I went to bed, some of the game music was stuck in my head. When I went to read LOTR: The Fellowship of the Ring in bed, it was still stuck in my head. When I slept, I had a really weird dream of Super Mario World. When I woke up, the music was still stuck in my head. Even after listening to songs by Jenny ROM for half an hour, the songs were still stuck in my head.
