Tesco begins music-download site
Tesco, the UK's biggest supermarket chain, is launching an online music service on Monday which it hopes will rival Apple's market-leading iTunes.
Demand has grown for music available over the internet and Tesco estimates the UK market is now worth £25m.
Tesco said its digital music store will use Microsoft's Windows Media Player and will charge 79 pence per song.
It plans to offer more than 500,000 tracks and says its system will give users improved sound quality.
"Music buying is changing," said Laura Wade Gery, chief executive of Tesco.com.
"We know that for the first time dads are spending more on music each week than their teenage sons."
