Fattmack shared his thoughts on his career

SoundCloud named the Alabama rapper its Ascending artist in November. In a brief Instagram message, McKenzie Haynes said his hometown, Mobile, shaped him into the person he is and the way he makes music.

The rapper stated that "one of the best parts" of his music was that fans related to it. He also shared that he told "the truth" through his music and felt no shame about expressing his "pain," noting that many artists did.

Haynes told SoundCloud that he treats music like therapy, and fame has not changed things for him. The 20-year-old claimed that he coped with his own music, just like the fans.

"Me getting bigger hasn't changed the way I connect with listeners. I care about getting bigger, but I really care about the music because the music is my therapy too. It's not just the fans' therapy. You know I actually cope day by day with my own music," Fattmack said.

The rapper shared in an interview with Viper magazine in June 2025 that he was inspired by fellow rappers Juice WRLD, YoungBoy, and Big Yavo. Haynes also stated that Big Yavo is his cousin.

He also noted the most vulnerable moment in his career was when he wrote a song about his relative Smaky and his death. Fattmack shared that he started crying while recording the song.
