The Temper Trap are an Australian indie-rock band whose breakthrough became one of the most-licensed songs of its era. "Sweet Disposition", released in 2008, was a soaring, chiming anthem built on a glittering guitar riff and Dougy Mandagi's falsetto, and it found a vast audience after featuring in the film (500) Days of Summer and a flood of adverts and trailers.
That ubiquity made the song far bigger than the band themselves. The Temper Trap released further albums to a loyal following, but nothing approached the reach of that one shimmering anthem, which became shorthand for a whole strain of yearning, sync-friendly indie.
On streaming, "Sweet Disposition" sits near 886 million plays, while their next most-streamed track, "Love Lost", trails at around 107 million. That puts the ratio above 8, past our 5.0 line.
By our measure The Temper Trap are a certified one-hit wonder, though they remain an active band with a real catalogue. Theirs is a classic licensing-era pattern: a song whose emotional, widescreen sound made it irresistible to filmmakers and advertisers, and which became so tied to those moments that it has stayed far ahead of everything else they made.
