Write Tags To File
You can write tags to file by right clicking tracks ➡ Use ➡ Write tags to file
With the Tag Writer you can update your music file tags (ID3 tags) so they are identical to your Lexicon database.
Your tracks will already look good in your Rekordbox, Serato, Traktor, VirtualDJ or Engine DJ after syncing but if you use your music files in another program (e.g. a music player) then you can mirror the changes with the Tag Writer.
You can select any field you want to write or skip. So you if just want to update your track titles but leave the rest as-is, you can do that too.
