Napster has signed-up the UK Post Office in a deal that will make pre-paid download vouchers available at 16,000 Post Offices across the UK.

The Guardian describes the move as an attempt on the part of Napster to, "take on the marketing might of Apple's iTUnes in the run-up to Christmas."

Because Napster offers an offline way of buying prepaid access to its services, the company hopes to attract less tech-savvy customers, perhaps relatives buying gifts for others.

It also allows younger music lovers a high-street route through which they can legally and autonomously buy access to Napster services, without using a credit card.

Two vouchers will be made available: green, which offer access to Napster's subscription services, and blue for permanent downloads. The company is also offering quantity discounts on music sales.
