Alphabetically order the music list

[Emral]

Is your feature request related to a problem? Please describe.
It takes frustratingly long to skim the list of built-in music, especially because it doesn't fit on a 1920x1080 screen.

Describe the solution you'd like
It would be a lot easier to find things if the list was sorted alphabetically.

Describe alternatives you've considered
A search box within the drop-down would be a higher-scope solution.

Additional context

Forgot to tell you: some days ago I took a brief look, and this can't be done quickly by built-in flags of the combo-box itself, but it's possible to implement the thing if I change the algorithm of the combo-box list filling with keeping every item index being properly assigned to the actual music ID.
