Feature Request: Listen to Spotify while playing! – Mental Math Cards Games & Tips Review

Love the app, you start to feel the improvement after a few short rounds a day. It’s this hidden guilt I have, being not-so-great at simple addition/subtraction/multiplication/division problems. Thank you for your application. Only request I have is to add the ability to listen to my own music while I play. Thanks!
