+1 for Gapless. My library is not nearly as large, but it’s still plenty quick (no noticeable delay) with my 1 digit gigabytes library and IMHO the best native feeling media player on Phosh/GNOME Mobile.
It also does the Album -> Artist -> Song thing (which made me notice that I still have not fixed every error in metadata I managed to add to a part of my Library by blindly applying musicbraiz suggestions via Tagger, but that’s just a me thing).
This. Also, most AppImages are x86_64 only. If they don’t explicitly say it’s for aarch64/arm64 you are going to also need some fun architecture translation (box64, fex, …) to make the thing run. At that point, it’s in many cases easier to try building from source IMHO.
PS: Good luck on Wayland can also be added, given probonopd’s (AppImage inventor) stance on Wayland. I’d advise to not waste time with AppImages on #MobileLinux.
