I don´t want to put down Taylors achievement, and for sure, Madonna is not as popular as she was cause when I started following her around 99 she was everything in a very different world we were living in. The thing is Taylor´s popularity will have an end too. And let´s see how is she remebered 40 years later. The world is changing so fast we don´t know.
To me, artists like Michael Jackson, Madonna, Streisand, Whitney, Madonna, Beatles..are above everything we have these days. They are icons not matter the current popularity. Their songs are hyms forever.
I really can´t sing any lines from a Taylor Swift song, she is really not very interesting for me But the same I never liked very much Gaga, except I know some songs from her.
Madonna was a product, but also an artist, changed everything, made history, and will be an icon forever not matter what. Let´see this today artists how are they remembered 30 years later.
