Group by album artist

Hello, I've got a new iPod touch 6th gen and am having trouble with the artist names- lots of them are under various or unknown artist. For example Oasis' definitely maybe album is listed under oasis, but morning glory under various artists. I had an old iPod which did the same thing, but in settings there was an option to "group by album artist" which I just turned off and it fixed it. This option isn't in the settings page on my new iPod, anyone know how to find it or fix it otherwise?
