I understand what you're saying. You can't help but feel that you're missing something, because so many others like her and talk about how unique she is.

If you are genuinely interested in figuring this out, sit down and listen to her first album, all the way through, without doing anything else at the same time. Sometimes the reason you don't "get" music is you are not really hearing it that well. Your mood and thoughts at the time have a huge effect.

Personally I find her songs kind of boring, but ten years from now I might go back and listen and suddenly go "Wow, I get it now." That happens to people all the time, tastes change, and it's ok.
