My partner’s system on stable branch had a working (but out-of-date) version of spotifyAUR 1:1.2.42.290-1. Updated to 1:1.2.47.364-1
Spotify proprietary service is also accessible via a web browser
There may also be spotify clients available as appimage, flatpak or snap package
Those are the usual choices if users want to use repository packages
Signal user in other topic has switched to Testing branch
inexperienced users could switch back to stable branch once they have the updated package
