I found that when you are in creative mode , the game only plays music that can only be heard in creative mode (such as "creative3.ogg")but dosen't play the music that can be heard in all modes when the player is in the overworld (such as "calm1.ogg")

In Java Edition, the game plays all the music that can be heard in the overworld.

Thanks a lot if you can fix this. 

Because I'm going mad hearing all the same musics .QAQ

By the way，this problem also exists on Android Devices.
