How do I combine identical albums on iTunes?

How can I combine two albums on iTunes? 10pts?

• From Katy Perry's CD, Teenage Dream, there's all the songs except for California Gurls in one album and California Gurls in another. I'd like to combine the two albums together so all of her songs are in one album but how do I do that? All the names, years and artists are the same.... Thanks! 10pts to best answerer.

• Answer:

  If you want to be able to have all the songs play in one string or chain or something just put them in a playlist. Otherwise highlight all the files you want combined and choose "get info". You'll get a warning that you're about to change tags on multiple songs. Click "OK" since this is what you want. Type Katy Perry in the "album artist" box and whatever name you want in the album box. That should be enough.
