I didn't see anything about this in the documentation or prompting guide, but... is it supposed to be able to sing?
Since I am a fundamentally unserious person, I copied in the Friends theme song lyrics into the demo and what came out was a singing voice with guitar. In another test, I added [verse] and [chorus] labels and it's singing acappella.
[1] and [2] were prompted with just the lyrics. [3] was with the verse/chorus tags. I tried other popular songs, but for whatever reason, those didn't flip the switch to have it sing.
Oh wow, it's interesting that it sings, but the singing itself is terrible! That's maybe more interesting, it sings exactly like a human who can't sing.
interestingly not very similar to the actual friends intro - suggesting it isn't a matter of overfitting onto something rather common in the training data.
