Gave it a try on my phone couldn't find any way of turning off music without also turning off sound effects (assuming there are any). My mother hates noise, so I'm going to keep looking for one that maybe lets you kill the music without also killing the sound effects.
I'm sure she'd like to hear the reassuring shuffle sound of the cards, but she would hate the music.
Again, though, I do thank you for the excellent suggestion, and I will be sharing it with her. I just need to also find some other good alternatives.
