Hello Legasee,
Welcome to the forum.
If you change the tags of the files after importing them in Djuced, you must re-import them in Djuced for Djuced to update all their tags. The fastest way is to "Delete the Music database" (as tags are in the tracks, they are is not lost), but it will delete your playlists, so
- if the playlists are already in MediaMonkey, you can go in Djuced > Setting > About, and click on Delete Music Database,
- if the playlists are not yet in MediaMonkey, you should export your Djuced playlists in M3u, import them in MediaMonkey, then you can delete your Djuced Music Database, and reimport in Djuced both the tracks and MediaMonkey playlists.
remark: Importing >6k songs is long.
Hello,
No, 6K tracks is not a crazy library (mobile DJs libraries may often exceed 100K tracks), but it is not a library you can reimport at the start of a party, it is a library you should import at home when you have plenty of time.
Djuced 5 cue points and fixed beatgrid are stored in the audio tracks, so they are not lost unless MediaMonkey has an impact on them.
