Lyrically speaking of course. I can't remember which album it was but 'Ye had a listening party (I wanna say Graduation) and said a certain underground MC that he had worked with early on really inspired him and pushed him to improve lyrically. Later Phonte said it was him and he was mad because he'd rather 'Ye show him appreciation by giving him a feature or something.

It seems to make sense, both go for the funny/witty punchlines and also the introspective tracks about personal relationships (Big Brother & Roses/Doin' Me and All For You)

For the record, I don't think it was ever implied or stated that Phonte ghostwrote for him, just inspired him. Also, I smoke a lot of weed and may be making this all up/remembering it wrong.
