If your character could sing, which famous singer would they sound like?

My characters, Beleth and Leyak can alter their voices to sound like any male or female singer, respectively.

(I guess these singers count as mildly famous lol)
Enni sounds like Holly Drummond. Her bf andrew (Our Supreme Lord and Overseer) sounds like Alec Benjamin. Fen currently has a younger voice, but eventually he'll sound like Stephen. His bf Berlin also kinda sounds like Alec Benjamin, although the actual voice-claim is this guy Anders I like. Zantya sounds like Taylor Swift or something ig. Flo would sound like this lady Noga Erez who's really cool. Morgan would possibly sound like AJR if he didn't talk like a high-school girl. Dodger sounds like Little Dragon. Kineta would be a female Macklemore lol. And I guess Esme would sound like Billie Eilish? A little cliche for her character but whatever XD
