Napster's British online music service has boosted its offering by a further 200,000 tracks. As of today, Roxio's U.K. download service boasts 700,000 titles. The company however remains tight-lipped on its sales volume since going live as a legitimate service on May 20. A spokesman said "we are very pleased with our numbers," but declined to comment further.

According to Napster, the additional repertoire covers a wide range of genres: rock, alternative, dance, pop, R&B, jazz, country, blues and hip-hop. It also includes exclusive material from David Bowie and British acts Elbow and the Zutons.

Napster's bolstered content offering comes as rivals Apple and Sony prepare to launch their respective download services in Great Britain. Apple has given the clearest indication yet that it will press the button June 15 on the British version of its iTunes Music Store. The computer firm will hold a "special event" that day in London. A spokesperson would not comment.

Sony's Connect service is expected to launch in Britain at the end of June, although no specific day has been reported yet.
