I am new to MP3tag. I have a problem that I have difficulty with in that almost every artist uses the same album names i.e., essential, greatest, etc. It would seem that finding cover art would be easier if the search included the artist name as well as the album name. Is this something I'm missing in doing cover art searches. Quite often I get a list of possibles that don't include the artist i'm looking for.

Which web source are you using?
If it is the amazon one, then you can safely add the artist name in the query box.
