Songfacts®:

• The epitome of Philadelphia Soul, "Didn't I (Blow Your Mind This Time)" is a heartbreaker, with the guy in the song getting his heart broken by the same girl over and over, yet still going back for more. He keeps trying, figuring his persistance will pay off, but every time he's disappointed. After his latest attempt, he asks, "Didn't I blow your mind this time?" but the answer is no. It might be time to fold the tent.
• Delfonics frontman William Hart wrote the lyric, with the group's producer, Thom Bell, adding the music. Bell and The Delfonics come together at Cameo-Parkway Records in Philadelphia. At the time, the group had five members and played instruments. Bell wasn't impressed with how they played or with the vocal talents of one member, so he reduced them to a trio (one guy joined the military) and had them just sing - Bell himself played many of the instruments on their early recordings.
  
  In 1968, an executive at Cameo started a new label called Philly Groove and brought The Defonics (and Bell) with him. Their first single with the label was "La-La Means I Love You," a big hit that got them off and running. They ran off a string of minor hits until 1970, when "Didn't I (Blow Your Mind This Time)" got them back near the top of the charts. Bell left soon after to work with another Philadephia start-up, Philadelphia International Records, where he produced The Stylistics. He started getting pigeonholed
  as a maker of slow, often melancholy ballads, but showed his range with The Spinners, leading them to a string of hits from 1972-1977. The Delfonics didn't do nearly as well without Bell at the helm, and broke up in the mid-'70s.
• This song has been covered extensively, by the likes of Aretha Franklin, Regina Belle, Jackie Jackson, Millie Jackson, The Trammps, Maxine Nightingale, and Patti LaBelle. The most successful cover, and also the most unexpected, is by the boy band New Kids On The Block, who took it to #8 in 1989. Their version was originally released on their self-titled debut album in 1986.
• A new generation discovered this song when Quentin Tarantino used it in his 1997 movie Jackie Brown, which uses it as a plot device.
  
  [PLOT SPOILERS]
  
  First, the bail bondsman character Max Cherry (Robert Forster) is having coffee at Jackie's (Pam Grier) when she puts the record on and grooves to this song - Brown and Cherry have a conversation about how she never got into "the whole CD revolution." Next, we see Max Cherry at a record store in the Del Amo mall buying the Delfonics album and then driving around in the car listening to it. We're supposed to get the idea that this middle-aged white man suddenly listening to the Delfonics indicates his growing infatuation with her. Finally towards the end, a highly agitated Ordell Robbie (Samuel L. Jackson) is riding with Max in the car on his way to what he thinks will be the return of his money, but he's actually getting set up. Whoops, Max left the Delfonics in the radio, and Ordell has a moment of suspicion when he remarks that he didn't know Max liked the Delfonics - it suggests that Max and Jackie might have become quite close and thus could have hatched a conspiracy behind his back.
  
  It also bears mentioning that Jackie Brown seems to have become the least-popular Quentin Tarantino film among his fans. It has more to do with timing - it came out right after Pulp Fiction and is a much slower-paced film (based on the Elmore Leonard novel Rum Punch), and how do you follow an act like that? Nevertheless, it was Tarantino's love letter to the '70s and Super Fly-type exploitation flicks.
• The song shows up in the 2019 Euphoria episode "The Trials and Tribulations of Trying to Pee While Depressed," and in the 2021 movie The Many Saints of Newark.
