These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base - Some of her fans react in a horrified fashion when she breaks into a different genre of music.

Critical Dissonance - Critics gave Pieces Of You mostly lukewarm reviews, but that didn't stop the album from selling more than 10 million copies in the US alone and granting Jewel a Grammy nomination for "Best New Artist."
