She has some nerve especially after he helped out her talentless self
She was forced into those sessions by her record label or they threatened to shelve the album, he also refused to promote it alongside of her. It's also a piss poor production, so no, he didn't do ****.
Lets be honest Pharrell started to pay Azealia dust after he emailed her the file for ATM Jam, which, thanks to him, is the weakest beat and chorus she's put to her name yet.
