Okay, we’re all totally over hearing our favorite songs in the background of One Tree Hill episodes, ever since Josh Schwarz dropped a big fat alterna-bomb on primetime with boob-tube A&R The O.C. and every show thereafter became a wash of minor-key power chords and plaintive wailing. But when an moderately arcane ethnomusicologist-esque DJ/producer is WRITTEN INTO THE SCRIPT of one of the cheesiest/most mainstream teen franchises since Patty Duke, we kinda have to take a moment to wonder what the hell is going on in the writer’s room over at The CW. Last night on 90210, when explaining why he and his girlfriend are made for each other, the character played by Tristan Wilds (the dude from the fourth season of The Wire) says, “WE BOTH LIKE DJ/RUPTURE.” WHATTT! Either the screenwriter was consulting Wilds as to what DJs he’s into, or the screenwriter was like “OH YEAH DUH, PRIVILEGED BEVERLY HILLS TEENS ARE TOTALLY, TOTALLY INTO GUARACHERO AND CUMBIA!” Maybe they have better taste than we thought? We’re pulling for a guest appearance next. We’ve already written the plot: So the girl he’s dating finds out that he’s still in high school (she’s an older woman) and dumps him because, ew. But then they GO to a DJ/Rupture gig (one where he’s DJing all obscure dancehall maybe), they meet him and he gives them sagely advice about how age ain’t nothin but a number, and they get back together. COME ON! Watch the show after the jump… the moment comes at about 12:40 in a beach scene.
