Apple plans to underline its link with music and popular culture with a launch at Glastonbury Festival this week, Macworld has learned.

While details remain scarce, third-party reports suggest the plan will emerge on Friday June 24 at the East Dance stage, where the first act up (according to the official Glastonbury Festival website) is called, "iTunes present..."

Further research reveals that the Dance stage will be opened up by the winners of a competition run between iTunes and Hit40UK. This asked entrants to create a five-song iMix of tracks they felt would be ideal to open the Dance stage this year.

Essentials cards

"Runners up will also bag themselves some great iTunes Glastonbury Essentials cards which get them 75 tracks of the hottest Glastonbury tunes on the iTunes Music Store," the competition page explained.

Apple's Glastonbury Essentials compilation is worth £19.75. The concept of imminent iTunes "Essentials cards" suggests an extension of Apple's existing band promo cards - collectible iTunes cards with band-specific artwork and special codes that let users download tracks from a specific artist or album. These cards are distributed as tickets to Apple's "Live from London" events, for example.

Meanwhile, the next version of iTunes is expected soon.
