* AllStarCast
* TheBechdelTest: Rarely passed (since the two most promenient girl + girl conversations are between [[AlphaBitch Trina]] and Mina, who are constantly trying to get Nick Mallory), but notably refferenced in the episode "Girl Fest", where Laney is trying to discuss "important stuff" (namely, music and shared interests) with a feminist model rock star, and is throughly disappointed when she is obsessed with stereotypical girly things.
* DevelopmentHell
* HeyItsThatVoice: [[Anime/SailorMoon Prince Sapphire]] is the lead singer, guitarist and founder of Grojband.
** He steals lyrics from [[WesternAnimation/{{Beetlejuice}} Lydia Deetz's]] diary, of course if you prefer [[Franchise/ResidentEvil Claire Redfield]] that's cool.
** [[WesternAnimation/{{Caillou}} Caillou]] is on bass, pretty good for a four year old.
** [[Literature/{{Wayside}} Louis the Janitor]] rocks the keyboard.
*** Speaking of ''Wayside'', looks like Pricipal Kidswatter is known as Mayor Mellow these days.
** What do you know? [[WesternAnimation/{{Sidekick}} Kitty]] [[{{Pun}} is still a sidekick!]]
** [[ReallyMe Jenny Donkers]] is still a huge fan girl.
** [[WesternAnimation/JacobTwoTwo Principal I.M. Greedyguts]] and [[WesternAnimation/{{Rupert}} Rupert Bear]] run the KentBrockmanNews.
** The school's party critic is played [[WesternAnimation/TotalDrama Chris Mclean]] (If TheDanza has any indication).
*** Speaking of ''WesternAnimation/TotalDrama'', Harold looks a lot like a floating extraterrestrial orb, Sam's still a gamer but seems to have lost weight (although at one time he was a genie with a spitting disorder), Lightning's a DJ, Gwen's still a goth, and it wasn't the first we've heard Nick Mallory sing.
* MissingEpisode: "No Strings Attached", albeit in certain states due to the "Straight into Heck!" joke.
* NamesTheSame: No, Corey [[Film/TheWizard spring his emotionally disturbed brother out of an institution, join forces with a resorseful girl so that they can make it to California for a video game tournament, all while dodging his parents and a sinister Bounty Hunter in the process]].
* NoExportForYou: The remaining episodes of season 1 can only seen in France, Italy, Australia, Latin America, Poland, and the UK.
** The [=DVD=]s for Season one can only be brought from Mexico, almost all of South America, and Australia.
* OfficialFanSubmittedContent: The contest winning "Wicked Cool Transitions" from the website.
* ScrewedByTheNetwork: While it's understandable that the new episodes haven't been airing, there is no excuse for Cartoon network to refuse to air reruns. The show was only being aired for 2 months before it was taken off the schedule and the network was airing the then-new episodes awfully fast, the show finally came back to Cartoon Network nearly a year later, but only limited to being watched on the "Watch Cartoon Network" app instead of being aired on the network itself....about two months later however, the show along with the episodes were pulled out of the website, which means you're stuck with the epsidoes in the foreign languages on You Tube.
* SeriesHiatus: Currently on this in both the United States and Canada, hopefully will be back on the air sometime this year. WordOfGod suggests that the episode "Rockersize" could begin with Corey telling the viewers [[VideoGame/KidIcarusUprising "Sorry to keep you waiting, everyone!"]].
* TalkingToHimself: The members of the Newmans are voiced by their Grojband counterparts, which also leads to CrossdressingVoices.
* WhatCouldHaveBeen: Corey's voice actor would've been the same person who voiced Nick Mallory, and his original name was Tre Trippin.
** Despite being musically multi-talented, Laney was originally the band's drummer.
*** Which counts as double, as that would have immediately made her an {{Expy}} of [[ScottPilgrim Kim Pines]].
** Larry was originally named Lenny.
*** Likewise, Lenny was also originally named Larry.
* TheWikiRule: [[http://grojband.wikia.com Grojband Wiki]]
* According to WordOfGod, [[http://neptoonstudios.tumblr.com/post/58429754344 Corey and Trina are raised by a single father]] [[http://neptoonstudios.tumblr.com/post/58599183195 and there never was a mother; he adopted them on his own]].
* WorkingTitle:
** The original title for "Soulin' Down the Road" was "Christrina", a reference to {{Christine}}.
** The original title for "Curse of the Metrognome" was just "Metrognome".
** The original title for "Girl Fest" was "Girl, You'll Be a Festival Soon".
** The original title for "A-Capella-Lips Now" was "Unplugged".
