I guess she definitely wrote a majority of Nude Beach a-Go-Go and Ariel just changed it for his album. In her The Process interview back in January she said she had an indie-rock song on the album that she wrote the bass, guitars, etc for. And I can't think of any other song that is anywhere near rock.
I would definitely say the notes on the cover are the horns from MC because she also says she has a house song on the album and she wrote horns into it herself.
This album really is just Azealia all the way through and I love it. 1991 was too short to get her personality to come through, and Fantasea had too many collabs. This truly
feels like Azealia, in the same way Born This Way
feels like Gaga and BEYONCE
feels like Bey
I can see why it's her favourite track.
Except I like Florida Kilos 
Log out and never return. Bye.
