Styles of singing?

HARRY

Think of a famous pop star known for his solo career after being in a boy band, whose first name fits here.

This clue plays on the name "Harry Styles," the famous singer, by splitting it into two parts. "Styles" is presented as a hint toward singing techniques, but it’s actually the last name of Harry, making the full answer his first name. The question mark signals wordplay, suggesting you shouldn’t take the clue too literally—it’s a nod to the pop star rather than actual singing styles.
