Please note - Spotify is an unsupported custom package
Althogh you can install spotify-launcher from the official repo - this does not make Spotify supported nor endorsed by Manjaro
spotify-launcher
Spotify has a free linux client but prohibits re-distribution, so this is a freely distributable opensource program that manages a spotify installation in your home folder from the official spotify release server.
