JoJo/YMMV

Ear Worm: "Leave", "In the Dark", "City Lights", "Never Say Goodbye", "Pretty Please" "Why Didn't You Call" "Like That", "Good Ol'", "Baby It's You" and "Anything"
Growing the Beard: "The High Road" is way more focused and cohesive compared to her debut.
Narm / Narm Charm: "How To Touch a Girl" has elements of both.
Sweet Dreams Fuel: "Never Say Goodbye", "Anything", "What You Like", "Let It Rain", "The Happy Song", "Sunshine", "Homeboy", "Breezy"
Tear Jerker: "Boy Without A Heart", "The High Road", "Note To God" "How to touch a girl", "Just a dream", "Keep on Keepin' On", "Exceptional".
Wangst: "Fairy Tales" falls into this; she was 12 when she sang it. It's about she, genuinely as a pre-teen had given up on love because of one little break up, at the age of at most 13.
- Opening every era with an break up song could fall into this too.
