t it were a 30-year-old singer, everyone would be wondering what went wrong technically
Actually that's not true. If someone sings badly live it's always called out
Irrelevant of age.
Madonna has never been a great singer. Her ability levels are in capturing rhe mood of the day and releasing songs that are popular, catchy, that people can sing along to, along with her sense of the dramatic, her performances, her videos. That's where her skill set lies.
There is no doubt at all that many songs Madonna has released are good songs, catchy and hugely popular because of it, and that capture the mood of the day.
I also wondered if she couldn't hear herself though, but ultimately if you're a singer with as many years experience as she has, you should be able to sing your own songs in tune.
I'm not sure if she gave too much to the actual performance in rehearsals , and focused less on the singing, resulting in what occurred, but I suspect she focused heavily on the choreography, the messaging, the staging, her outfit, her make up, the dancers outfits, and so little on the actual singing that it resulted in a poor singing performance.
Either way, I'm not sure she's waking up this morning to the reaction she expected.
