When downloading a CD album, if it contains different artists, the album is split up into separate albums/icons. How do I get all songs into one album (just like the original CD)?
Generally, in iTunes, all you need to do is fill in an appropriate Album Artist to keep things together. For older iPods each track from the same album should have the same artist, or be marked as a compilation where appropriate. For iOS devices you may need to go to Settings > Music > Group By Album Artist > On.
