Are you looking for music player with support for Shure or just any music player?

If just any music player can consider AIMP. I like it as it can choose output such as OpenSL or AAudio, I got some file that was encoded using MP2 which Android internal sound system can't playback it. It also easy to create new playlist by folder and re arrange orders, on the list in playlist can see a lot details such as each song from which folder, duration for the playlist, total file size, also can customized the display name. When create new playlist and add folder if all the files have same album name then it will rename the playlist as that album name, this makes it very convenient to create new playlist. It's "now playing" screen also adjust volume by swiping vertically, it also support a lot custom gesture. It have bookmark, favorites, and queue functions. It have a lot others stuff that you can customized. Cons is it cannot directly play file from it's internal folder, browser, you have to add into playlist first, but you can add all folders into a playlist and treat that as browsing folders.

Previously you already tried AIMP? Any issue with it?
AIMP also can stream songs from NAS or PC. It use SMB protocol.

I thought you stream using DLNA? It doesn't have SMB?
