Albums are not in genres, because genre is per song. This makes sense because a movie soundtrack, say, or any various artists compilation, can have songs in different genres on the same album. But if you look at your collection in Songs view, where you see columns for Name, Time, Artist, Album, etc., you can add a column for Genre. Just right-click on the column headers and click on Genre.
Thank you - that works. And I see I have all the Ray Charles in the correct genres. And Dizzy's, too. You can search for artists you think should be in more than one genre. But to find out if there are artists you've incorrectly put into more than one genre, you need to plough through the list. A bit of a drag. But, well, you can do it.
