very true but Cher had a number 1 single in her early 50s. But you could argue that Believe was an exceptional track. Or that compared to the 90s our culture is even more ageist and that a woman in her 50s couldn't now achieve what Cher managed in 1998.
That is true I think Kylie and Madonna can surprise us still I even think Cher still could. I don't like how ageist music has become I am a fan of these artists always have and always will.
