* AllStarCast: "One Love", which had Akon, Music/NeYo, Music/TheBlackEyedPeas, {{Music/LMFAO}} and Kelly Rowland. "One More Love" used those above but added {{Rihanna}} to that mix. "Nothing But The Beat" featured NickiMinaj (twice), Music/FloRida, Music/LilWayne, Music/ChrisBrown, Music/Ludacris, Music/{{Usher}}, Music/SnoopDogg, will.i.am, Jennifer Hudson and JessieJ.
* HarsherInHindsight: his decision to use Sia's demo vocals for Titanium. To say she didn't want the new attention she'd gotten so soon after her intended retirement from being a singer is an understatement. She later revealed that she was nearly DrivenToSuicide over it.
* LoveItOrHateIt: You can either like him for his highly danceable EarWorm-rific tunes, or despise him for being [[ItsPopularNowItSucks WAY too mainstream.]]
* SeinfeldIsUnfunny: Guetta has not seen much American success since 2012 because his turn-of-the-decade style of EDM was seen as out of date and rather poppy compared to the more hardcore stylings of Calvin Harris, Zedd, and Avicii.
* SignatureSong: "Love Is Gone" and "Titanium" are the best candidates, as in each case, the vocalist isn't famous enough to overshadow Guetta on the song. But once Music/{{Sia}} became more famous on her own the song became less associated with him and the former has now taken the lead.
* SuspiciouslySimilarSong: The hook of Music/{{Usher}} & Ludacris' "Rest Of My Life" is similar to Afrojack's "Can't Stop Me".
** The backing track to Flo Rida and Nicki Minaj's "Where Them Girls At?" sounds very similar to "Sexy Bitch", one of Guetta's other songs.
