Jennifer Lopez became a global pop and R&B star in the late 1990s, and her 1999 single 'If You Had My Love' — specifically Rodney 'Darkchild' Jerkins's remix, with its subtle pitch-corrected vocal touches — is the record T-Pain has cited as his first exposure to what would become his signature effect. His two-year search to track down that tool eventually produced a far more extreme, genre-defining use of it.
