Tear Jerker: Beatmania
The song Scorpion Fire, whilst pretty epic in the game cut, has a full 8 minute version in the OST. Trust me when I say that you will have tears in your eyes from 2:40 onwards, in particular the section beginning at 4:15.
When Jason Michael Borenstein (who portrays Michael a la mode) died, this sure caused the fandom to shed a tear or two.
