In a Diet Coke commercial aired last night during the Oscars telecast, viewers got a taste (like Pepsi, but different!) of a song that, more than a year and a half after its release, can’t seem to stop getting placed in movie trailers, ad campaigns, and TV shows. Watch its latest cameo, below:

“Sweet Disposition,” by Australian dance-rock outfit Temper Trap, first came to mainstream American attention early last year in the trailer for not-so-commy rom-com 500 Days of Summer; then again in this Chrysler campaign, and once more with feeling (and an actual name check for the band) in this Rhapsody commercial.

It’s a great song, one that almost guarantees a nice little booster shot of serotonin in every viewer’s ad-addled brain. But is it time to put a moratorium on co-opting it to sell everything from soft drinks to sedans? The Rhapsody ad—using music to sell a music service—at least makes sense. And we hate to begrudge the band both the wide exposure and the residuals one hopes all this usage is putting in their wallets; take the money and run, boys.

But with its multiple appearances on TV shows, too (the song has been used in episodes or promos for 90210, Greek, The Good Wife, and The Deep End), it might be time to either retire the track from big and small screens, or give it the inevitable SNL digital short treatment, a.k.a. The Imogen Heap/Marissa Cooper OC Memorial Razzie for Pop Cultural Ubiquity, before it hits “Hallelujah”-style saturation.

What do you think, readers?
