“I can say that it’s over.”The opening line of Johnny McGuire’s debut single, “I Can’t Even,” is a blunt introduction to the song’s story line: an overview of a man struggling with the dissolution of a meaningful romantic relationship.The timing unintentionally fits McGuire on a professional level, too. It’s his first solo single since the breakup of Walker McGuire, a duo that released three singles from 2017 to 2019.
