If you've followed Thug's life before the rico trial then you'd understand that it makes sense why Young Thug's post-rico music sucks
I really don't know how some people expected him to come out with a hunger and reinvigorated passion for making music when we all knew he was never gonna be the same or better.
Forgetting all the drama, betrayal and mental struggle he went through during the 2+ years he was in jail, The man is on probation for the next 9 years of his life. With that, he's practically walking on thin ice cause of the industry (Rap) he works in.
He can no longer freestyle in the booth as he did before which was a huge factor in his popularity rise due to his creative head-turning lyrics. He now has to think of every word he says and any music he wants to release has to go through a legal team to avoid any trouble with the law.
Even lines/words that would be morally grey get cut and he has to rerecord everything which you already know is tiring and discouraging to him due to the kind of artist he is whose creativity is on the spot rather than curated!
