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.
YMMV: The Jonas Brothers
Awesome Music: "World War III", "Shelf" and their cover of "Poor Unfortunate Souls".
Base Breaker: Nick Jonas and Joe Jonas' solo projects. Some love Joe's solo album Fastlife, while others hate it, the same for Nick Jonas And The Administration's Who I Am.
And when Nick and Joe cover each other's songs, there will, inevitably, be fights that break out over whether or not the brother covering it is doing it better than the original.
Lines, Vines And Trying Times qualifies. Fandom's pretty evenly split on whether to love it or hate it, since it's something of a departure from their previous straight-up pop rock sound.
And a new one: With Joe and Nick using Precision F Strikes, the fandom's pretty divided as to whether it just doesn't bug them, or whether it sounds cheap and is just an attempt by the band to get people to see they've "grown up".
Their new single "Pom Poms" has already turned into this. There seems to be three camps about it: 1. They hate the lyrics (and the [leaked] music video) and miss their old sound, circa "A Little Bit Longer". 2. They like both and see no problems with it. And 3. the group who think it's over-hyped and doesn't live up to it.
"Pom Poms" is even a base breaker critically. There's some who think it's a great pop song that's fun, and then there's some who hate it and its lack of meaning.
Covered Up: Their "clean" version of "Year 3000" is better known than the original version in America (the All Music reviews of their albums seem to think they wrote it).
Ear Worm: When You Look Me in the Eyes, Burnin' Up, SOS.
Pretty much all of their songs, at some point or another.
Fanon Discontinuity: Lines, Vines And Trying Times, since it's a Base Breaker, and some fans prefer to pretend it (and the brothers' respective solo careers) never happened.
Fridge Horror: Following the theory that "Black Keys" is about self-harm, what can the line "the lights out never had this bright a glow" mean other than the singer being tempted with the idea of suicide?
Made even worse with "Wedding Bells", which all but outright states that the singer got drunk upon hearing the news, as well as the line "if I fall asleep, then wake me up cause I'm trying to see the light", which continues with the implications of suicidal thoughts. (And, like "Black Keys" and "A Little Bit Longer", Nick wrote "Wedding Bells" on his own.)
Friendly Fandoms: Surprisingly friendly with the 30 Seconds to Mars fanbase. The Jonas Brothers reunion show at Radio City Music Hall was aired live on Mars' online music pay-per-view event service, VyRT. This made them the first band besides 30 Seconds to Mars themselves to stream a concert with the service. The Mars fanbase, the Echelon, took time on the VyRT site and other social networks to answer questions about the service, help overseas fans figure out what time the stream would be airing, and explain to the parents of Jonas fans that, yes, their credit card info WILL be safe if they pay for the ticket. Most Jonas Brothers fans appreciated the help. Of course, there was the occasional cross-Fan DumbFlame War and some Echelon members were merely assisting Jonas Brothers fans because the financial and critical success of the Radio City show stream would benefit VyRT and Mars in the long run.
Hilarious in Hindsight: "Video Girl" is about girls in music videos and how they aren't going to do it again. Following his break-up with Taylor Swift, Joe Jonas dated (and then split with) Camilla Belle, who was in the video for "Lovebug".
Hype Backlash: From their own fandom over "Pom-poms", which has been so hyped by the group (and a good chunk of the fandom) that some people feel disappointed.
Iron Woobie: People tend to perceive Nick as this, if not all three of the boys, and it's referenced in "Hollywood".
Now we're making headlines, primetime, saying 'what a story'...
To be fair, it is somewhat justified, because before they were picked up by Disney, they worked for Columbia, who basically dicked around with them and kept pushing back the release of their album, which got very little advertisement aside from what the boys did personally, and very nearly went bankrupt before Disney signed them.
And, of course, Nick has his diabetes.
Launcher of a Thousand Ships: All three. Joe's been paired with his girlfriends, his brothers, any one of the other Disney stars, male or female. Nick's gotten the same treatment, and even Kevin's gotten in on it. (And one of the most popular pairings for Kevin is him and Zac Efron.)
