* CoveredUp:
** Everyone seems to remember that "Every Time We Touch" is a cover, but not many know the original. It was by former Music/MikeOldfield collaborator Maggie Reilly. And "Faded" was originally an even more obscure song by Australian singer Kate De Araugo.
** "What Hurts The Most" is an aversion. Rascal Flatts' version was the biggest hit in the US, but Cascada's was the bigger hit everywhere else.
* GermansLoveDavidHasselhoff: The group is more popular in the US, UK, and maybe Asia, than in their native Germany.
* IAmNotShazam: Natalie Horler is sometimes misidentified as Cascada.
* MemeticMutation:
** Pick a fandom from the mid to late 2000s, any fandom from the mid to late 2000s. Chances are, that fandom has at least one {{Shipping}} FanVid set to "Everytime We Touch" somewhere on Website/YouTube, and indeed, there may be ''multiple'' [=FanVids=] featuring that song in a single fandom. Possibly a DiscreditedMeme now, though.
** "Miracle" was big in 2006 and Website/{{YTMND}} for being associated with the "Gravity Cat Not Amused" meme.
* MisattributedSong: Mainly songs remixed by the same [=DJs=] to sound like Cascada but aren't actually done by them.
* SuspiciouslySimilarSong: A lot of people noticed that their entry in the 2013 Eurovision Song Contest, "Glorious," sounded a lot like last year's winning song, "Euphoria," from Swedish singer Loreen.
