Game freeze

A game freeze refers to the instance of where a game's controls lock up disallowing the player to play the game normally, but every other aspect of the game functions properly. Through different glitches, different varieties of game freezes have been found. Sometimes music may be frozen on the current note but sometimes the music will stop completely. On rare occassions, the music will still be playing.
