Fresh Prince Of Bel Air Remixes, also filed on Know Your Meme under the title Fresh Prince of X, are mash-up tracks that pair Will Smith's rapped vocal from the theme to The Fresh Prince of Bel-Air with instrumentals lifted from other songs, film scores, and video game soundtracks1. Each entry keeps Smith's autobiographical lyrics about being born and raised in West Philadelphia intact while swapping the original funk backing for something completely unrelated2.

Individual uploads are usually packaged with a fake album cover that crops Will Smith's face onto whatever the paired track's original artwork was3. The comedic DNA of the format traces back to the Bel-Air bait-and-switch copypasta, a text prank on 4chan's /b/ board around 2004 that opened as a serious message before abruptly switching into the theme song's opening lines3.

Producers typically take an a cappella or vocals-only version of Will Smith's theme song rap and layer it on top of an instrumental at a similar tempo. The paired track is often a recognizable pop single, movie score, or video game tune, and the finished upload commonly comes with a fake album cover placing Smith's face onto the original artwork.
