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.
It's worth noting that during her live performance at Lollapalooza 2007, she saw someone in the audience getting sick and stopped performing until they were helped. During this time, she bantered with the audience, asking them how they were doing.
Likewise, at an outdoor concert in Brooklyn in 2008, a sudden rainstorm soaked the audience. Regina left the covered stage, and returned with a bucket of water, which she poured over her head!
"Long Brown Hair" is sung from the point of view of a self-justifyingrapist, while "Belt" is a twisted, very, very Black Comedy about an abused woman and her abuser, alternating between both point of views.
Other songs can be more eerie and unsetting than something sung in that voice should be - the nightmarish "Ezra Pound/If You're Never Sorry" and "Apres Moi" come to mind.
They Changed It, Now It Sucks: Some reviews have derided Regina, particularly for her latest album Far, for smoothing out eccentricities, being overly cute and becoming commercialized main-stream pop. An example here.
The video for "Don't Leave Me (Ne Me Quitte Pas). It features Regina doing random stuff around an apartment and then a tiny, flaming guy with a trumpet appears out of the trashcan of stuff she just lit on fire.
