AOSP apps look and work terrible in my opinion. The music player hasn't changed since what, Android 2?
There's a reason ROMs like LineageOS develop their own alternatives. Most ROMs seem to use those open source alternatives rather than the apps Google abandoned with AOSP.
I was talking about the AOSP apps GOS ships, which is handful and doesn't include a music player. Apart from maybe the gallery app, I don't see any other as completely unusable. They already maintain Camera, PDF viewer, Vanadium, App store and Auditor
