Albums with tracks by different artists in itunes

Factual Questions
1

I have a lot of music already in mp3 format. When I import this music into itunes the albums with more than one artist show up in the viewer as different albums. How do I fix this?

2

Edit the album title in iTunes. Most likely, there are slight differences – an extra character, for instance – that leads to a different listing.

3

Thanks for the suggestion. However, the album title is exactly the same.

4

Is the “Album Artist” property (found under File > Get Info > Info) the same for all tracks?

5

No it is not. If I make them all the same things work like I want. What use is the album artist supposed to provide? As opposed to Artist?

Thanks for the help.

Often there will be a track or two on an album that’s coproduced with another artist. You want that artist credited for the song, but for it to be categorized with the rest of the album.

On the other hand, how is iTunes supposed to know two albums with the same name but different artists aren’t really two different albums (think “Help” or some other common name).

Album Artist is intended to clarify this.
