Luigi Pipe Glitch

[Rune the Koopa]

When Luigi enters a pipe in a level editor level, (I think it happens in story mode too, I have not tried it yet) the music doubles making the same song play twice at the same time. This can be fixed by pressing Mute ON and OFF. Has anyone else encountered this glitch?

This glitch has been known for long. The only fixes are a) the mute button and b) playing with Mario.
