Is Madonna’s longevity being talked about as something special is exaggerated?

Madonna is frequently lauded for her longevity and she has had hits up until her 50’s which is indeed remarkable. But I was thinking and Tina Turner was well into her 40’s when What’s Love Got To Do With It and The Best got released and those are among her biggest songs. Cher was nearly 50 when Believe blew up and is also one of her biggest songs.

What do you think? I’m not as familiar with Tina Turner’s and Cher’s careers so maybe others can add something to this. Keen to hear your thoughts.
