LM3 King Boo fight + credits with 100+ E.Gadd's Lab themes playing

There's a glitch that allows you to play the E.Gadd's Lab theme anywhere in the game. A funny thing about it is that if you load a save after making the music play, you can play the music over itself as many times as you want. What you see in this video is the result of me loading a save over 100 times and stacking another track each time. The game's audio engine did not enjoy this.
