A Bug for fixing and suggestion

• When adding songs (putting songs in the dedicated “Music” folder in the app directory), the app seems to stop loading new songs—even after refreshing—past ~150 songs added into that folder. It is either this, or that at the ~150 mark, if you delete a song and then attempt to re-add it through the Music Folder, it will not appear automatically, forcing you to use the “Open Files” button strangely.

You should add a way to edit the file’s tags or lyrics inside of the app.

Response from developer

Hi if you have any issues you can make one on github. Thanks for the kind comment.

One of the best offline music player

My main problem is that you have to have your downloaded music saved to the cloud because every time when the app updates, all songs would stop working

Best at what it is

I was searching for a music player to play my music locally offline since I plan on moving away from music subscriptions to owning my own content. I was genuinely surprised that the entire app store didn’t have a single ‘offline music player’ that worked without paying anyone money. This is the only app that does what it says it does, it’s also extremely fast at indexing content, I was able to import hundreds of high quality music within seconds, does a good job at fetching metadata online as well. Really good work to the devs! 💪

Excellent music player

Great app, I think is better then vcl player

‼️ Bugs for fixing

When large loads of songs are applied (120+ files), the app can begin to break. It may clear your custom playlists or remove all of your songs.
