I know that WAV files arent able to have album art attached to them so thats fine, but a lot of these files are MP3s and the album art still isnt getting imported. Is this a traktor thing? What I read made it seem that Traktor writes the album art you add to the file but maybe that is not the case. Is there a way to get these album arts in without doing it manually?
After import to Traktor go to Track Collection and click "check consistency " and your covers are back
Sorry, the album art is going missing after importing to lexicon, not traktor. When I go from traktor to lexicon to rekordbox Im losing the covers.
Lexicon does not sync (export) the covers to RB. In RB you have to reload tags and the art will appear (except for WAV).
If you sync to Traktor, there is an option to enable album art on the Sync screen.
