Not hearing default music

[Apex]

So I may be legit dumb and overlooking some options here, though when I am trying to go back to the default music (the backgroud music if you will), it won't let me. The tablet will continue having a song selected even if I hit pause, and there's no "stop" button that I can see.

Anyone got an idea to bring the default, non-track background music back after using the tablet once? Their music, track or not, is incredible for this game.
