Moosync is a customizable desktop music player with a clean interface. Listen to music from your favorite service (Spotify, Youtube, or self-hosted Subsonic, Plex, Emby instances) inside one app. Available on Linux, Windows and MacOS.
Still in active development with bugs here and there, but hey! it works fully with only lyrics fetched from Genius being broken as of writing. But everything else is excellent there are even community made extensions that bring additional streaming services to the app. The setup is relatively complicated for first timers but the documentation available on the official website is excellent.
I am pleased to know about Moosync's launch on ProductHunt. Been using this product for over a year, and it works flawlessly. A great set of features, good UI & availability on all platforms make this product unique. Congratulations @ovenoboyo !
