It might merely be identical to what occured on A Series of Unfortunate Events in the Finale where all the main character did a performance. It doesn't necessarily need a 'Singing Curse' to explain it considering we're already aware that all major storylines are wrapped in 6x19 therefore this episode is just a stand-alone episode which I doubt will even be Canon. If this was a DVD/Bluray bonus feature, then sure it could be non-canon, but the fact that it is an episode of the show means it can't really be anything other than canon.
