Can iTunes add images for mp3's created from recording Vinyl?
I have created over a 1000 mp3's (320 bps, 441hz) from recording Vinyl. Obviously i can manually create images for these files individually but will take quite some time, so i wondered if iTunes could automatically create them. I have tried to select all images in library by getting album artwork but it just tells me the following statement 'Getting album artwork requires you to sign in to the iTunes Store using an Apple ID. Please go to the iTunes Store and sign in or create a new Apple ID.' i have logged into itunes and it still tells me the same thing. Could anyone point me in the right direction? My files are saved on my mac. Many thanks
