I have an album listed three times.

I assume this is a single-artist album, not a compilation one. There are usually two reasons why an album gets split up in the way you have described.

Either;

1. some songs have guest artists listed in the artist field or,
2. there is a difference in what is typed into the artist or album field, such as a space after the last word (which you will not notice).

If it's problem 1. then one work round is to put the additional artists into the song name field and set the Artist field as the main artist. (User tt2 has a different method, he may well add to this thread. If he doesn't notice this thread, check out his posts, you'll find him listed as a top participant in this community.)

If it's problem 2. the best way to fix that is to copy the artist name from one song into all the other songs and do the same with the album name . (You may notice the extra space if you highlight the whole field.)

Generally setting a common Album title and Album Artist will fix things.

For deeper problems see Grouping tracks into albums, in particular see Tried that, there are STILL too many covers!
