About a week ago, I reset my pre opened up Music and *bam* no Album Art

it was working fine from the day i got it till then. I used iTunes to sync, but i cleared the folder, synced with songbird(with ipod support plug-in) and no album art still, so frustrated i deleted the folder again and straight up copied the music into the Pre drag and drop. STILL no album art.

Now people who say normally, "ITS THE TAGS ITS THE TAGS!", if it was the meta data, then why was it working until now, 3 months and no issues. I didn't even sync the pre to cause the issue, it happened after a simple restart out of dev mode
