Apple's iTunes this week is offering exclusive material from Goldie Lookin Chain, a new single of the week, and more.

This week's new free single download comes from Guitarra De Pasion and is called Mi Tierra. The music's described as fusing, "authentic South American music traditions with original melodies performed by acclaimed Colombian guitarist Juan Carlos Quintero". The track is taken from concept album, Guitarra De Pasion.

New Celebrity Playlists are available now from Erasure, Depeche Mode, Destiny's Child and William Shatner.

Goldie Lookin Chain's 'Live in Newport' album is also available exclusively through iTunes, while more mass-market modernist irony comes with the site's promotion of the 'Little Britain' audiobook, narrated by Tom Baker.
