- Cult Classic: They're generally well-respected and have a strong community within the indie rock world, but it'd be a struggle to call them "amazingly successful." Gareth half-jokingly acknowledges that this what the band has become this, once noting that many of the bands that have opened for Los Campesinos! in the past — like Vampire Weekend, Two Door Cinema Club and Imagine Dragons — have become highly successful while LC! remains a cult band touring mid-size clubs.
- Ear Worm: It can be said just about their entire discography, especially their more poppier numbers, such as "You! Me! Dancing!", "By Your Hand," "Hello Sadness," and "Avocado, Baby."
- First Installment Wins: While the band still has a strong cult following, Hold on Now, Youngster... is considered their most popular, successful and — depending on who you ask — best album.
- Funny Moments: During the "A Good Night For a Fist Fight" live recording of "You! Me! Dancing!", the band starts off with the first chords preceding the Epic Instrumental Opener... and then plays the opening riff of "Smells Like Teen Spirit" before continuing on.
- "Coda: A Burn Scar in the Shape of the Sooner State" is a poignant track, presumably about the death of a loved one, but it dips into narm with the lines "I fall to my knees / My piss-soaked jeans". One would assume it was from shock and fear but... yeah. It manages to recover from it, though.
- Gareth's hair in the music video to "International Tweexcore Underground." It might be befitting of the twee fan he plays in the song, but that doesn't stop it from looking ridiculous on him.
- Signature Song: "You! Me! Dancing!" from Hold On Now, Youngster... is considered their most popular song, but each album has also had a standout track, such as "We Are Beautiful, We Are Doomed" from the album of the same name and "The Sea Is a Good Place to Think of the Future" from Romance is Boring.
- Tear Jerker: Oh, they've got a lot.
She said one day to leave her, sand up to her shoulders (waiting for the tide)
- "The Sea is a Good Place to Think About The Future" is a beautifully melancholy song about the narrator's broken, self-harming lover who appears to be contemplating drowning herself.
To drag her to the ocean, to another sea’s shore (This thing hurts like hell)
But what did you expect!?
- "We Are Beautiful, We Are Doomed," despite how utterly joyous and exciting the music is, is about a very real disintegration of a long-distance relationship. Once you realize what the song is actually about, it can be hard to listen to, especially if you've experienced something similar.
- A good amount of songs from Hello Sadness can fit as tear jerkers. But with a title like that, did you expect?
- The title track, while it's still very energetic musically, can be very emotional since it appears to be about a close relationship on the verge of failing. Despite his repeated insistence that Hope Springs Eternal, it actually makes it feel more hopeless; making it seem like he'd rather stay in futility and lie to himself than be alone.
