Ever bought a game never even thinking about whether the soundtrack will be good, only to be blown away by the sheer catchiness of some of the songs? That's what this topic is for. Feel free to chat about some of your favorite unexpectedly good game tunes.
For me, the biggest one has to be just about any of the WarioWare games. You wouldn't think a series built around five-second minigames would have particularly good music, but I'll be damned if I wasn't humming music from these games for days after playing them. Mike's Song, Mona's Pizza, Dr. Crygor's theme, and Dribble & Spitz's music (from the original WarioWare) were particular highlights from the series for me.
