It sparked massive criticism from netizens. While some questioned the song choice, considering how hard the vocal range is in “Sweet Venom,” others hit back at his poor vocals, especially as he’s already debuted and been in the industry for five years, with some just saying he couldn’t sing and that any praise was “low standards.”
