Anyone else think the joke about 'a universe where we turn into bunnies' was a reference to Buffy's "Once More with Feeling"?
Without spoiling too much...as both a Trek fan and a lover of musical theater, I think they managed to find a sweet spot between the two genres. The songs were above average for a 'very special' musical episode, and all of them did something to move the overarching theme of 'connection' forward in some way.
Kevin - I don't know if it's fair to compare "Subspace Rhapsody" to "My Musical", only because the setups are very different. SNW's characters are aware they're singing, so the songs (and how they're handled in-story) are more meta (and in multiple cases, Uhura prompts a song into being vs. it happening organically); by contrast, the songs in "My Musical" are taking place inside the head of a patient (Stephanie D'Abruzzo), so the characters have to commit to the musical theater convention of randomly singing when the mood strikes because that's how the observer is interpreting it. "Once More with Feeling" is arguably more analogous to "Subspace Rhapsody", although it does share the "make the music go away event" convention with "My Musical" (as opposed to OMWF, which actually ends on a song).

Although part of me wonders what would have happened if Uhura had blasted some Sondheim into the subspace fold.
