Also, if you have all the files in that album selected and you get info, then in the Grouping area, put the artists' name and it will group all those songs under that one name. This name appears under the albums' name so that is why Artist is the best choice. Or if it is a mash up of artists like Now 17 or what have you, then you can just have it the album name or the remixer (like all songs remixed by so and so)... I have that and compilation checked...
EDIT - I found out I was wrong, the thing you want the same on all the songs is the "album artist" once again, you can just put like the album name if all the songs are by different artists...
