Use case: Production process of new album: create an album in Reprtoir with some rudimentary metadata, like preliminary titles. Define a watch folder for the album on your machine, and drop track-numbered audio files there, for Reprtoir to upload. Make a playlist and send to team. Update tracks with mixes as work progress; playlists will automatically be updated; fill in metadata as work progress, and album be ready for Release after final master is put in Watch folder.
