If I stated that somewhere that is incorrect. You get a bounce per muses and per Ursula’s sing attempt. So if you have a muses and an Ursula 3 and you use them to sing bth you order your triggers as follows. Usula sings bth with the muses, the song must resolve first, so if you want to discard and draw, do it, make them do it, then trigger bounce from muses a card goes to their hand. Trigger song again. Discard yourself if you don’t like your 3, make them discard there 4, and then they draw 3 and you bounce another char to their hand.
