I think that was meant to be her defining character moment, much like how she had to give up just having another moment with her mother in the Crystal Labyrinth; being the only one who had to brave that trial only to be reminded of a big personal loss rather than sacrificing it and gaining it back like with Stella's beauty and Tecna's emotions (even though Rainbow could've easily made Musa sacrifice her hearing to the same emotional effect).

Even worse is that, with Musa, she always has to accept that her mom is gone. She already wants to carry on her dreams of becoming a renowned singer like she's carrying her torch for her.
