On Linux, on all players I know, and I imagine on other OSes, the sorting works first according to the artists on the album before the artists (where it may be guests).
Why doesn’t it work this way in Music app to let albums complete in Artists view?
Would it be another better reader than default’s one?
Default Music player is pretty minimalist. Your can’t for instance search a title or an artist by it’s name (no search function).
I personally use “Fossify Music Player”, which 100% open source, available on AppLounge or F-Droid. It gets everything most people need (including equalizer, playlists, etc…)
I really like it.
my music library isn’t tagged very well to understand, is this issue describing what bothers you?
in any case, A15 /e/OS ships with upstream Twelve fork music app that could behave different in this (and has its search function restored).
Yes, that’s it. Many albums are distributed by an artist (band) when titles may be tagged as some artist + some guest = a fake artist for those titles. That’s because Music app doesn’t take care to sorting by Artist of Album but by Artist only that may be fake. Imagine a compilation album you couldn’t sort as a whole album. It is a complete mess.
I don’t really understand what “A15 /e/OS” means. I own a FP4 updated to Android 14 /e/OS 3.0.2 and basic apps should be up to date too.
Fossify Music Player isn’t described as opensource in App Lounge and has v. 1.0 only in my F-Droid (Classic).
In all cases updates are a full PITA on /e/OS. Many times App stores aren’t working, it’s still true in /e/OS 3.0.2. I’m tired with App Lounge/F-Froid/Aurora. Why sources can’t be the very same nicely grouped in a working App Lounge?
This is exactly the reason why tag based players are unusable crap. You will never have proper consistent tags in your music files, whatever you do and how much effort you pay on this. And the larger your music library is the bigger is the problem.
The only solution for this problem is a folder and file based player. The folders and files on your disk are easily manageable with every damned file manager. You can arrange them as you want, you can copy, move, rename and delete them. The only thing you need is a player which is able to operate on folders and files instead of tags. The stock Music app isn’t able at all. Have a look at Foldplay (my default for a year now), or SicMu, or Lisna. Also foobar2000 and vlc can work with folders very well.
I second the recommendation of folder based players like sicmu (very basic and simple, I like that) and foldplay etc.
A problem with SicMu is: it makes always an artificial 3s gap between files when playing. I hate this really and this is indeed the reason why I don’t use it anymore. I have a lot of music where one track fades into the next one, sometimes which intended transitions (remember Pink Floyd albums from the 80’s). Also classical music is often cut into 20 peaces regardless of that it should be a single movement of a symphony or similar (remember Richard Strauss’ Alpensinfonie). SicMu seems not to be able to play gapless. (At last this has been the case about a year ago.)
Yes 
I remember, we discussed that before some time ago …that did not bother me yet, probably due to my music choices, don´t know, but just in case: I still have foldplayer installed 
too bad, yet still: working as inteded (apart from not being gapless…)
No, my fault, it has moved to GitLab (from GitHub). The last release there is from 2020.
Thanks, unfortunately I tested Foldplay is unable to read .flac files (but read .m4u very well). It shows an empty folder. Otherwise it works well showing embedded covers like all my music. I didn’t check if it is able to manage foreign characters like accented ones and special punctuation like : … ç à etc. as Music Player can’t manage UTF8 (I have music files tagged on iTunes but I try to tag everything again with - mainly - Strawberry on Linux Mint).
I found no result for Lisna in App Lounge.
Foobar2000 looked promising but it seems unable to browse sub-folders on my 1TB SD card. It found only 13 files when I have a lot of artists folders with albums folders inside. It looks incredible for an app able to sort by folders. Edit: OK, it took time but it’s OK now. There’s no gap between files and it’s able to read UTF-8 in files names and tags. It is my preferred.
I know VLC on Linux as too much complicated and I’m afraid about it. It isn’t just a music player.
Yeah, sorry, I have no experiences with .flac files (because of their enormous size). Most of my files are .ogg and .mp3.
I would not use strange characters too much in file names. Especially I had serious issues with the simple : (colon) in a filename because it is used as the path separator in UNIX paths. But on Windows you can easily make such files … I always pay attention on simple file names.
Lisna is mentioned here (with some pictures). The original website (Google Play Store) doesn’t seem to work anymore. But you can still download recent APKs here.
foobar2000 has long been my default player. It can handle large libraries, mine has more than 60GB. It uses an own algorithm for searching files, independent from the system indexer. So you can even exclude your entire music library from the indexer to unburden it by putting a .nomedia file in the top most directory … foobar2000 can handle this very well.
Try vlc, it’s really not more complicated than others. (AIMP is complicated …)
No issue with characters, Foobar is able to read all names from files and tags. It’s the solution.
Android 15 for /e/OS - it’s around the corner and brings along Twelve, a new default music app. That link had a way to install it directly via apk download, it could work on A14 already. If the sorting is still as wrong in your eyes with Twelve as with Eleven (default music app in A14), one could work on a patch to upstream to solve this.
But default players always have some feature lacking you want. I heard good things on musicolet.
I’m happy with Foobar 2000 so I’m able to wait for a complete A15.
For now I just have to re load 3-4 albums with embedded covers from Linux. I’ll think to check all tags and titles before to move my music on /e/OS. Easy enough.
I’ve recently found (last paragraph) subsonic support be useful when home, no need to sync files. Twelve can do it, but 3rd party apps better / more compatible.
But I don’t use a Mac anymore to read my music. I still own an old one but all my music is now on Linux Mint and on a Synology server.
My only concern about Mac is I own an Yamaha CD player with Airplay as available source but I wouldn’t use my Fairphone to play my music on it as I have fare more albums on Linux Mint . It’s far from /e/OS. 
it was just the OP being a Mac user - Navidrome (that implements subsonic the API) is multi platform. Actually easier to setup on linux things or Synology with a container. Ok I stop the advertisement it was helping me listening to older stuff again while at home - as I only keep a seasonal rotation on-device.
My mistake, I said “Music app” that’s a Mac app but I guess it’s Music Player on /e/OS. Some music com from an old Mac but I taggued it on Linux Mint since years.
