As I mentioned the album does not have its own article Are you saying that it would better to have a tiny separate article for the album alone and then a cover would be okay It makes more sense to me to keep it all together and since this is the only place that the album will be mentioned then the cover should be allowed here There doesnt have to be pictures anywhere on WP but I think there is a pretty big precedent for this sort of thing on musical films for sure on Indian films which are mostly musicals
