The music being a part of the in-game universe is the weirdest interpretation of the canon I've heard about so far.

I imagine that this line referenced some music that Muffet played. She did do a synchronized dance herself, so that's that.

Besides, if this were true, it would be the only instance of music being "canon" anyways, so I don't think it was intended, really.
