OK, sure, the obvious answer here is that D4L were an inspiration on all kinds of Southern "ringtone" rap, pop rap, novelty dances, etc. And that's probably true, albeit one data point in a whole line of singles. And no doubt group member Fabo, a true star, was influential, particularly in the South.
But perhaps D4L's most underheralded influence has been on the current California production style. "Laffy Taffy" hit No. 1 on the charts, and was released in January, 2006. (That same year, The Pack released "Vans"—a nominally snap-influenced smash that launched the career of, among others, Lil B.) (And let's not forget DJ Quik's late-period snap classic, "Can U Werk Wit Dat.") The current style of DJ Mustard—which he's branded "ratchet"—was, according to his collaborator Ty Dolla $ign, influenced by snap as well. Ty was instrumental in the early days of Mustard's career, and describes the "Rack City" beatmaker as having popularized a sound they'd been creating for a few years.
"We’ve been doing that sound since ‘07. We wanted something that wasn’t so … jerk?" he told us, referring to the style of dance-oriented teen rap that popped off in mid-2000s Los Angeles. “Something more ‘G.’ [Ratchet] is all the same drum pattern as ‘Toot it and Boot it.’ A blend of some West Coast shit with some down south snap music, but sped up.”
