Tsskyx got it right here. I reached the same conclusion, though from a slightly different way.

First off, yes, the line very well was a reference to the music Muffet played. She already mentioned the sychronized dance with the spiders, so why can’t it be just that?

Besides, if music is canon, then so must be minibosses, because Spider Dance actually shares a lietmotif with the other bosses (I have a full list of my analysis on what lietmotif represents what here). And if minibosses are canon, well that leads right into the world being canonically a game, which makes it code, which leads to a whole mess of problematic and strange implications.

Really, the rule I use to differentiate canon laws from non-canon game mechanics here is simple:Is the mechanic referenced by anybody, or abused by anyone? (Flowey and Sans are usually the prime ones who do this) If so, it is canon, but if not, it’s not. And it has to be a direct reference, not something that could be a reference to that, but very well could also reference something completely different, like in Muffet’s case, Flowey’s final speech being used as evidence that the Player is canon, and so on.. If an alternative explanation exists without any holes, it’s usually correct.
