Wave Tags and iTunes 12.1.0.26

[Rudj]

Well I'm very surprise !
Today I decide to listen a wave track in iTunes, first I see the album artwork in the reader; I Open the track in the finder and see it with the iTunes logos; after I just click on it and the logo disappear (I promise, I'm not a magician !); when I listen again the wave track there's no more art album and I can't drag and and drop another one ?
Is it a bugg or a new special tag format in iTunes ?
Thank you for informations

Best regards

Frank

With iTunes you are better with AIFF which it can tag and read dBpoweramps tags.

Thank You Mr Spoon, I've found THIS about the problem I met; do you think that UTF-8 is responsible of tags non codification ?

I do not know, I do not use iTunes. It is possible it has any number of issues.
