Hey @WallyDelux, thanks for looping me in here @NoiseRiser
Up until only a couple releases ago of Engine Prime, all tags were only saved in the Engine Prime database, they weren’t written back to the file at all. We changed this for the common tags (ie Song, Artist, Album) and write these back to the files (File type & permission dependant) but not for shared DJ centric tags (ie BPM/Key) because changing this on the file can cause unwanted behaviour when using different DJ applications with the same tracks.
I believe star rating has fallen into the second category, similar to how rating has been implemented in iTunes, rather than Rekordbox. I wish i could explain this in a bit more detail however i’m unable to at this stage we have some work scheduled for a future update to Engine Prime in regards to the information we read/write to/from files and overhaul the workflows around that experience and make them more tailored for a DJs workflow.
I hope this kinda helps? let me know if you have any further questions
