As far as I know she writes a lot of her own material, and the songwriting is very good if you're a 20 - 40 year old female.
She is a rare talent. I'm just really sour on the whole concept of celebrity.
Me too.
If someone is a very popular singer, they're probably a good person to ask for tips about how to become a popular singer; How to market your music; How to sing; How to protect your voice from environmental hazards.
They might be a good person to ask about how the record industry operates; How a recording studio works; and How to cope with the behaviour of fans.
The thing that astonishes me is that so many people seem to think "That person is a very popular singer; We should ask their opinion on politics, religion, war, virology and immunology, climate change, and the economy!"
There are actual immunologists you could interview. Why the fuck are you asking a popular singer's opinion on how (or even whether) a mass vaccination campaign should be managed?
Elvis Presley famously got huge numbers of people to go get vaccinated against Polio. That's great. But it's also evidence of a massive cognitive flaw in humanity - How the hell did we survive beyond the neolithic era, with brains that prefer the advice of popular people, over that of people who actually know about the things they are giving advice about?
It kinda works, when the experts are the ones feeding the information to the celebrities (as was the case for Elvis), or if the celebrity in question happens (coincidentally) to be well informed; But getting the right result for the wrong reasons doesn't protect against getting the wrong results next time around - and we see plenty of examples of famous people successfully promoting ideas that are positively harmful.
