Version 5.0.5
This app was pre-installed on my smart phone.
It does support the composer tag!
If you select a composer the result is tracks.
Nicely sorted alphabetically so totally useless.
I have the Title tag pre-fixed with the composition.
You can’t see the movements.
Rotate helps a bit.
You can do a search.
It list Albums then Titles. Looks like the Composer tag is not used in the search.
