A song by a Melbourne band called The Triangles has hit number one on the Spanish charts after it was used in a TV ad for the Spanish beer brand, Estrella Damm.

The Triangle’s sound - described as a mix of psych-pop, indie-folk and rock – has appealed to a global audience with the five piece ensemble’s song ‘Applejack’ hitting the top of the iTunes Top 10 singles chart in Spain.

The group’s YouTube clip has had over 1, 500,000 views.

Melbourne-based music supervision company Level Two submitted the song to Estrella Damm to be used as the soundtrack for the beer brand’s summer ad campaign created by its agency Villarrosas, in Barcelona.

In May, The Triangles were flown to Menorca to appear in the commercial.

The song was released by independent Australian record label Half a Cow and could be described as a ‘sleeper’ hit having originally been released on the album 'Magic Johnson’ in 2005.
