Working with Depeche Mode in the US, Apple has begun experimenting with fresh ways to improve the digital music buying experience.

In a new approach being offered to US iTunes Music Store users, Apple is offering Depeche Mode's new "Playing the Angel" album for pre-order through its music service - but there's an extra incentive, too.

Fans who pre-order the record between September 13-26 will also receive a password that offers the opportunity for the fan to buy up to four tickets for selected dates on the band's North American tour.

Tickets will be available to the fans (from September 20) from Ticketmaster four days before the tickets go on sale to the public (September 24).

This is the first time digital downloads have been involved in this type of promotion.
