Katamari Damacy. It's got one of the most infectiously joyous soundtracks of all time -- an eccentric, richly-produced, and incredibly catchy melange of funk, salsa, bossa nova, experimental electronica, J-Pop, swing, lounge, bamboo flute, hair metal, buoyant parade music, soaring children's choirs, Macintalk fanfares, and the single best theme song this side of Super Mario Bros. And beyond being insane earworms, many of the tracks have surprisingly deep and meaningful lyrics.; my favorite is probably the beautiful "Cherry Tree Times", which I've seen described as "[using] the gameplay mechanics as a metaphor both for the twinge of nostalgia we could feel even in childhood toward our younger selves and for the experience of falling in love."
