O man, people give Madonna way too much credit for her lack of talent. She’s a great marketer of herself, one thing for her legacy, she spawned all the other talentless hacks we have nowadays.
I’m going to say Trevor Rabin. Incredibly talented at many different instruments (including vocals), great songwriter, and he was incredibly handsome. After he left Yes he stuck to scoring film soundtracks and faded into obscurity.
Madonna is among the greats of the past 30 some years. There are more talented artists but it’s not like she has no talent.
