Hi,

There is probably some bug in amarok (current svn), which causes not displaying album covers fetched from amazon, when the album name contains single quote sign (\'). Covers are downloaded properly, but are displayed only when you click \"show fullsize\". In any other place stands only generic \"question mark\". Even in cover manager.
So there is probably a problem with generating md5 sum filenames of thumbnails (50x and 100x), or something like that. I think.
