Version: 188.8.131.52 (using KDE 4.6.2)
I use different "setup" for Artist and Albumartist. This is for sorting purpose only.
I use Artist with "Firstname Surname" and Albumartist with "Surname, Firstname" (Mike Oldfield vs Oldfield, Mike).
The Applet "Albums" is showing nothing when I play tracks (from Mike Oldfield). The Applet shows "Album by Oldfield, Mike" and maybe the applet is searching Artist (Mike Oldfield).
Issue shows only by different Artist - Albumartist content.
Steps to Reproduce:
After typing same Information into both ID3-fields (Mike Oldfield) the issue was gone.
I use MP3Tag v2.48 with "ID3v2.3UTF-16" setting on a Windows PC.
