Wondering if anyone has had this issue. I do library management in iTunes, since TP3 lacks heavily here. I use AIFF because of ID3 tags and prefer to keep tracks at full quality. I’ve never had problems (over 5+ years). I recently changed the comments on all my songs in iTunes. All songs display the ID3 tags and artwork in iTunes and even in external tag editors. All songs are ID3 version 2.4.0, and clicking convert in iTunes everything is greyed out except create AIFF version. I’ve done a fresh install of Traktor Pro 3 and here’s what’s happening: 1. When adding to collection a handful of tracks are fine. All my new tags are there and Grid + Cuepoints are there. 2. Most of The other tracks when adding to collection I get an error “ID3-tags can not be read on...” 3. All my new tags are there but none of my Traktor data - grids, cuepoints, etc. and no Artwork. Things I’ve tried: 1. Check consistency in Traktor 2. Checked permissions on the whole directory structure and I have read and write privileges. Additionally: 1. In iTunes if I select a track and go to File > Convert > Create AIFF (which is the only option not greyed out) 2. It creates a new file, still in ID3 v2.4, and the only changes I see is to the file name. 3. When I add this new file to Traktor Pro 3 collection, there is no error, and Artwork is there... but all Traktor related info is gone. So it appears there is some issue with ID3 tags in the original file, although I can’t figure out what it is. Wondering if there is anyway or app to fix this - or anyway to force iTunes to re-update ID3 stuff or version? Otherwise I guess I need to re-convert these in iTunes (to the same format, which doesn’t make sense) and redo all grids, cuepoints etc.
