Ariana is clearly a feature lover, she had four features on DW and six features on ME. Who should she feature on AG4? I'd say 1. Madonna 2. Pharrell Williams (he's a major producer on the album) 3. Mac Miller  4. Drake 5. Nicki Manaj 6. Katy Perry 7. Lady Gaga 8. Miley Cyrus if she featured all these names I'd be happy. I'm sure she'll have less features then 8 but it'd be cool if she had all these.
