Music's Fatboy Slim and David Guetta, informally

DJS

Think of the people who mix tracks at clubs or festivals—this term is their common job title, often seen on event posters. It’s also the abbreviation for the role that keeps the dance floor moving.

This clue refers to Fatboy Slim and David Guetta, both famous electronic music artists who perform as disc jockeys. The term "informally" hints at a shortened or slang version of their job title—"DJ" instead of "disc jockey." Since the answer is plural ("DJs"), it covers both artists in one neat package. The clue plays on their shared profession while keeping it casual.
