Hi Mike,
Thanks for the link: so I delete the VLC cache files, and then only one song cover were corrected(the first song I played actually).
But when I play all the other songs, they all display a wrong cover(they all display the same cover from the first played song above!)
So I don't feel like removing the VLC cache each time I play a song...I believe there should be a other solution, but still have no clue about it
Thanks for any help.
