The program can only know whats been put in it's database. Have you any idea how many CD's are out there.
To give you some idea. Chcuk Berry info lists 233 CD's I'didn't bother to count how many they didn't have artwork on.
My music is genuine Rock N Roll. There is only info on about 40% of my albums.
I have also seen CD,s with Identical titles but by different artists which could lead to some errors
Can't help with update because mine doesn't work. Find info opens new window but nothing when I click update.
Try right clicking the pic, Do you get save as, if so save it to a folder on your desktop then copy and paste.
