MediaMonkey just isn't finding popular albums :s

Hey everyone,

I have been slowly organising my 140gb collection of v0/320 mps files. I have a mac and a pc and have been copying my collection back and forth to get everything tagged. It's just come down to album art now and I was hoping my last run would be using MediaMonkey but it's not happening.

Using the auto tagger album by album it's not finding popular albums on Amazon.com/co.uk. I'm having to use Discogs and tbh Discogs has terrible scanned artwork. So what gives?

Please don't judge me on my collection here...

The Black Eyed Peas - The E.N.D
Calvin Harris - Ready For The Weekend

I can find it on Amazon but MediaMokey is not finding it through the autosearch with Amazon. iTunes also doesn't find it. I have been using Picard and Rapid Evolution on my Mac to get album tags so assume they found it but can't remember. I'm just stumped as to why it's not finding things like. I don't really want to have to resort to google images and dragging them into iTunes.

Anyone got any ideas?
