!!The musician:
* CoveredUp:
** "Everybody's Gotta Learn Sometime", a cover of The Korgis. Also, he covered "Diamond Dogs" by David Bowie.
** On the receiving end, Beck wrote "Feel Good Time" with William Orbit, but deciding not to use it, allowed {{Music/Pink}} to record the song using the backing track he and Orbit had already prepared. The original Beck version leaked out later and is nowhere near as well known as the Pink version. To a lesser extent, Music/JohnnyCash 's cover of "Rowboat." ensured more interest in "Stereopathetic Soulmanure" which was otherwise an obscure album.
* EpicRiff: "E-Pro", and to a lesser extent, "Loser."
* InternetBackdraft: Beck beat out Music/{{Beyonce}} for a Grammy once, it got weird.
* MisaimedFandom: As mentioned on the main page, Beck does ''not'' like the fact that "Loser" was encouraged as a slacker anthem when he had spent several years being homeless.
* NightmareFuel: The [[JumpScare loud]] [[CarefulWithThatAxe distorted yell]] in "Where It's At", which sounds extremely inhuman and more like a tortured robot.
* SignatureSong: "Loser" is far and away his most popular song. "Where It's At" is a strong runner-up.
* StylisticSuck:
** That little silly solo part in "Girl". Unlike the rest of the song, it sounds like a bunch of random notes played on untuned guitar.
** Also, if we go by his initial idea, the lyrics to "Loser".
** His vocal delivery on the verses of "Gamma Ray" is full of stuttering and hesitant pauses, as though he was either nervous or just struggling to remember the lyrics, while the chorus is sung much more confidently. Beck himself has said "I was trying to sound as bad as I could, for a laugh".
** Various early songs, such as "Trouble All My Days" (from ''Golden Feelings'') and "Total Soul Future (Eat It)" (from ''Stereopathetic Soulmanure''), have Beck detuning his guitar intentionally badly, to create bizarre and hilarious music.
* SuspiciouslySimilarSong: "Up all Night" sounds a lot like Music/JustinTimberlake's Can't Stop the Feeling.

!!The anime/manga:
* EarWorm: Many of the songs, especially the opening.
* {{Engrish}}: Whenever any of the lead voice actors in the original Japanese dub attempt to speak English. Even if their characters have canonically lived in America for years. Averted with the American musicians, who are often played by actual expats.
* HollywoodPudgy: Koyuki, with no sense of sarcasm, chides ''Maho'' to not eat so much or she'll get fat. Unfortunately, that's [[ValuesDissonance Japan for ya]].
* {{Narm}}:
** ''GET THE FUCK OUTTA HERE!!!'' (Ryusuke calling out on Koyuki, after the latter unintentionally breaks a guitar the former had given him in an early episode. [[spoiler:Turns out that the guitar, which Ryusuke cherished for thinking it belonged to Eddie Lee, was a replica of Eddie's usual one, and all was good between them again.]]) It's only funny because of Ryusuke's accentized English.
** Averted in the English dub, where Eric Vale's lack of an 'Engrish' accent helps the line's effectiveness.
* SuspiciouslySimilarSong: The gentle guitar chords of "Moon On The Water" sound a lot like Ednaswap's Wacko Magneto version of "Torn".
* TheyChangedItNowItSucks: Many fans' reaction to Funimation's having to swap out Music/TheBeatles' "I've Got A Feeling" for an in-house Dying Breed song during the anime's climax in Episode 23.

!!The TV movies
* EnsembleDarkhorse: The Neighbour. It's telling he's been in every single movie/episode, the only character to do that other than Beck and Gunvald. Even Beck's daughter Inger has appeared in fewer films.
* MemeticMutation: The Neighbour's every single activities and Gunvald's fits of rage are known and lampooned by most Swedes.
