Bailamos

The harmony of "Bailamos" is built almost entirely on the Andalusian cadence (i–VII–VI–V), one of the oldest and most recognizable progressions in Spanish and flamenco music. The use of E major as the dominant rather than the natural minor Em gives the progression its characteristic tension and drive. Despite its simplicity — essentially a four-chord loop — the flamenco guitar textures and the Phrygian-flavored resolution lend the harmony an exotic quality that distinguishes it from typical late-'90s pop.

"Bailamos" was written by Paul Barry and Mark Taylor, the same songwriting duo behind Cher's worldwide hit "Believe." The track first appeared on a limited edition of Enrique Iglesias's 1998 Spanish studio album Cosas del Amor and was initially released as a single in parts of Latin America and Europe. After Will Smith attended one of Iglesias's concerts in March 1999, he invited the singer to contribute to the soundtrack of his upcoming film Wild Wild West, and "Bailamos" was chosen.

Released in 1999 as part of the Wild Wild West soundtrack, "Bailamos" fused flamenco guitar with contemporary pop production and became Enrique Iglesias's breakthrough into the English-language market. Written by the same team behind Cher's "Believe," the song rode the Latin pop wave alongside Ricky Martin and helped Iglesias secure a multi-album deal with Interscope Records.
