* EarWorm: Try "Alligator". In fact, pick a song on ''Sainthood''.
** "Everything Is Awesome", written with Music/TheLonelyIsland as the theme for WesternAnimation/TheLEGOMovie. The song's catchiness is even a ''plot point''.
** "U-Turn" and "Boyfriend" off of ''Love You To Death'' will never leave your head. Ever.
* MemeticMutation: Lesbians have a reputation for obsessing over this band.
** Similar to Music/TaTu, some fans were only interested in them at first (or inversely averse to) because of the assumption that they were incestuous. (They're not.)
* {{Moe}}: Also, they're tiny.
* TearJerker: They have quite a few, with standouts including "My Number," "100x," "Now I'm All Messed Up," and especially the break-up ballad "Call It Off."
