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 should be noted, however, that the Nirvana B Side "Marigold" was a Grohl composition that featured him on vocals, Grohl had already written and demoed most of the first album songs in 1992, and he had also released a self-released cassette album called "Pocketwatch" by Late!. However, these would have been of minimal interest beyond the most obsessive member, but if Nirvana had stayed, it's possible Grohl might have broken out on his own anyway, given his various abilities.
Broken Base: After the band refused to let their songs be featured on Glee, their fandom experienced mild turmoil over whether or not it was a good thing. Not that it particularly bothered Taylor Hawkins, for example, whose response to Glee in general was "Fuck that shit."
Their native US has Nirvana's shadow hanging over the band much thicker than elsewhere in the world. Whilst they sell many records and play arenas in the US, their popularity there is nothing compared to that in the UK, where in recent years they have sold out massive outdoor shows in minutes, months in advance. By Dave's own admission, the UK treats them like they are "the biggest band in the world", and while he can walk around cities like Los Angeles largely unrecognized, he gets mobbed on the streets in the UK.
Literally with 'Wheels'. Dave has mentioned on several occasions that apparently Germany is the only country where they can play the song with the crowd singing along. Most American crowds tend to be bored and most Asian crowds aren't bothered with it.
Growing the Beard: Many fans consider the 3rd album, There Is Nothing Left to Lose, as the band's best.
