Reply to iTunes not importing key tags into Traktor.

Hello.

I created a playlist in itunes from a folder of tracks (all of which have key tags) - but when opening the playlist in Traktor the key tag is empty - anyone know why and what to do about this?

If I import the files in Traktor (without using a playlist) then it does show the key tag, so the issue seems to lie with iTunes somehow?

Thanks.
