I've read all the help and tips.
My image is the right size, I updated it months ago. Every other platform has the new art work, iTunes however keeps the old.
Here is our RSS http://feeds.soundcloud.com/users/soundcloud:users:235619045/sounds.rss
you can see that the image is updated in the feed and has been updated for months, however iTunes keeps the old brown logo, and hasn't changed to the black and white one.
Can someone please show me what I'm doing wrong?
