Where does DJay store song metadata such as cue point?

Is there a database file and if so, where is it found on MAC? Furthermore, where is it stored in the case of tracks streamed from Spotify?

So it appears there is /Users/UserName/Music/DJay Pro 2/djay Media Library.djayMediaLibrary

What is stored in this file, and will backing up this file serve to backup all metadata (Cue Points etc.) in case of system loss?
