I have many MP3's with embedded cover art in them (bought them like that) When Windows Media Player plays one of these, sometimes it displays the correct cover but most of the time, it displays the cover from a song that was previously played, sometimes several days before!
I have had this problem for a very long time! And it survived and recent reinstall of Windows 7 (hard drive crash).
My problem is similar to this one but no solution has been posted.
If I try to reproduce the problem at this moment, what happens is that when I double-click on a MP3 in Windows Explorer (Windows 7, WMP12 not already running), the cover that will be displayed is from a MP3 I played earlier in the week, which we'll call (A). The cover display in the status bar of Windows Explorer is correct though. When I change MP3s, (Windows Media Player running this time), sometimes the cover stays stuck still on the cover of (A), sometimes it displays the good one. If I quit at this time and restart Windows Media Player with the same MP3, the cover of (A) is back again...
I do remember having another behaviour closer to the one described in the link, that is, Windows Media Player was lagging always one cover art, displaying the art of the previous song, but maybe that was with WMP11, I can't remember
Did anyone experience this problem and found a solution?
