It seems that there is a albumart problem. I recognized lot�s of false albumart when i looked at the files in foobar ( checked also with MP3Tag ).
So i looked at a folder of lot�s of songs from a-ha with different releases.
I made a update of all files through MB, saved and closed them. Opened them again in foobar … all files have the same cover. Opened again in Jaikoz, same result.
I am using v23 with UTF-16.
