I’ll skip the backstory and get to the point. I would really love to be able to use this application on my pc that uses windows, so that my music is somehow synced. Maybe have an option to hook up a google drive to the app, so you can have music available from it on both devices at once.I’m sure this next request would be way too much work or illegal, but I would love to see a way for music to be able to be played in the app as a streamed option like the discord boys have free streaming, but to be honest the way the app is right now is great simple open source and no trackers. I’m in love with it after moving from melodista bc they have ads and tracking and all types of things.

It's not the objective of the app too be able to stream but it's open source maybe futur apps will do that with cosmos as a backbone.

Great app!! I liked everything at the beginning, everything is comfortable and pleasant. But I've encountered a problem, now, when I go in, the first ten seconds everything is fine, and then everything just freezes. The app doesn't respond to touch or anything I'm very very sad. P.S. (English is not my first language, translated through a translator)
Really good music player. Lacking some quality of life/settings

I really like this app, it’s very clean looking and very simple to use. Plays music perfectly well and overall works well for my use case. The only thing I wish I could do was edit the titles, tags, artist, description, etc. for each song. Right now I have a few songs from the same artist but they show up under different artist titles and it would be nice to manually group them together. Overall this is just a nitpick and the app is great either way
Developer Response
Metadata editing will not be added on the app you can use other app to do that.
The exact app I have been waiting on!

Years ago I stoped using a MacBook Pro and when I did I stopped syncing my music. A bunch of my music is not sold on iTunes and was locally distributed by the artist themselves years ago. I keep a copy of all of my music on a nas that gave me limited access to it. Now I can load my favorites and take them with me again.
