I also had to pass this oddity along. I have quite a bit of music and an iPod, so obviously iTunes seems to be the appropriate application to use. Well, I got a sexy new computer a few weeks ago with some funds that had originally been budgeted for other priorities that never came about, so I used them to treat myself. Oh man, it's got an AMD dual core 64 bit processor, a 400GB hard drive, and 3GB of RAM. It's unbelievable how fast this thing is, and believe me, I've been pushing it trying to test its limits. I haven't found them yet.
Oh, sorry, back to what I was saying. So I took the 120GB SATA drive with all my music on it out of my old desktop and dropped it into the new hotness, then changed my iTunes settings accordingly to import all the music into its library. Because of this new level of performance available to me, I've started using the visual setting that scrolls and displays the album covers along with your song listings. As I listen, I'll import an album cover here and there, finding that sometimes iTunes isn't all that accurate. I happened to try to retrieve the album cover for Megadeth's Hidden Treasures, and I got this.

I did a search on this album, and all I found was what appears to be Heavy Eric's website, which I've honestly been a bit too afraid to really dive into. This is just the latest in a long string of borderline surreal things that have popped up these past couple weeks.
I kinda hope it keeps up, because I think I'd be really bored otherwise.
