Probably some. A lot of these new artists have hipster/fair weather fans to begin with. So if it's not cool to like him anymore, they'll jump ship. For sure anyone that liked Action because they liked Ghostface will jump ship. I'm sure his loyal fans will stay with him. I doubt he'll disappear or anything, but 2015 is already sealed up and filed away as a bad year for his career.
I know it's gonna be hard for me to listen to his music the same. I enjoyed 2-3 of his mixtapes and was never a die hard fan, but I was a casual fan on some level because I'm a big Alchemist fan, so I just wanted him to not clash with the production. So I was excited for Rare Chandeliers, was a bit let down by it, and then it grew on me some more. Even then, IMO the best verses on there were from Sean Price, Evidence, Styles P, Roc Marci, etc.
But I didn't like Action's debut album at all, and I've gotten kinda tired of his gimmick over the past year. I think his best lane is the chef/youtube/tv food show personality. Put it this way. I preferred his affiliates like Meyhem Lauren and AG the Coroner over him.
But yeah man. It's going to be really hard to hear him rap from now on and not think of Ghost.
