DnD requires give and take between what the players want and what the DM wants, and so there are some ideas I have that will probably never see the table, just because my players aren’t interested and I don’t have the confidence to pull it off if they were. This is one of them.
Pop Tartary* tastes like bubblegum and isopropyl alcohol.
Pop Tartary looks like Divine:
And sounds like these:
 
 
Pop Tartary Americana is: ruined future, nuclear science and black magic, leather vests, platform shoes, pop star prophets, glitter in the streets and blood in the water, go go boots, sweat sheen, garbage witches, strange frequencies and nightmare channels, sentient music videos, compulsory reality TV, weak reality, false eyelashes, record producer liches, Lady Gaga has a cult but Azealia Banks has an army, nasty cute, the devil wears Birkenstocks, occult street drugs, glass jewelry, Elvis impersonator priest/esses, Our Lady of Wigs, neon samurai, the Electric Saint, the Rocket Messiah, vinyl miniskirt is 18 AC, syringe demons 
Classes:
Noomancers tap weird subliminal Jungian frequencies to produce Magic-User spells; rely on radios and cell phones to work their art
Pop Mediums create servants from the psychic leftovers of lost fame
Gleaming Divas/Shining Adonises glammer their enemies with preternaturally good looks and eldritch voices
Neon Samurai fortify their martial expertise with the power of the electromagnetic spectrum
Henshin have turned sad fantasy into violent reality by actually gaining superpowers when they don costumes

Who’s Who of Pop Tartary:

Johnny Deluxe is the oldest vampire in Las Vegas
Marie Laveau is still alive and more sorcerous than ever
His Royal Majesty, The President of the United States of America is the iron-fisted monarch of the world’s greatest democracy
Adam is a superintelligent AI from Silicon Valley that has flourished since the end of the world
Monsters
Uranium Elementals, glowing nightmares born in the aftermath of the Incident
Discoheads have disco balls for heads and flail about with needle sharp claws
The Trash Dragon was born from a landfills and terrorizes the Southwest with its fallout breath
Big Crocadilly rules the luminously green swamps of Florida
Static demons crawl out of televisions tuned to the wrong sorts of channels
Paparazzi avoid direct conflicts, but love to snap pictures of you in compromising positions. Wagers of social warfare. 
Inspiration 
Blueprints of the Afterlife, Persona, Scissor Sisters, Diplo, Simon Green’s Nightside series (thoroughly mediocre!)
*by this I mean it is an anachronistic post-apocalyptic science fantasy setting like Richard’s Tartary and Jason K’s American Tartary, not that it is set in Asia
