Hamilton also has interests in music, saying "music has been a huge passion of mine since I was really young. I started playing guitar when I was 13. In here, I can be me, I can be vulnerable. I can show a side of me that people don't get to see". He features on Christina Aguilera's 2018 song "Pipe" under the pseudonym 'XNDA', though he did not confirm this until July 2020, when he revealed he had been writing and recording music for ten years.
