Not sure if you updated your music app, but it seems to run now. However I think there's some issues and improvements to be made.
Album view seems to be in some arbitrary order, and some on the list are not actually music, things like Download, Data, and QQ Mail. Some music players you basically set like this is my Music folder, and don't look anywhere else for MP3s etc.

The songs list only shows 6 songs maximum, with no fast way I can see of scrolling down. And with 48847 songs, it could take a long time to get to the bottom.
The font used, while stylish, is not very efficient at showing song titles. Maybe use the same font, that was used in the Album list.

Also the Genre and Artist lists aren't showing anything.
One of my uses for my phone is music, and I sometimes do like to try out different music player apps.
