Emusic, the digital subscription service that industry experts peg as the second-largest digital download store, had its biggest Christmas period since the company began trading in November 2004.

According to the firm, its subscribers downloaded nearly half a million tracks on Christmas day.

That total came as a result of doubling the number of new customer trials from Christmas day the previous year. The company now claims 400,000 paid subscribers, up from the 350,000 subscriptions base it announced in November.

"We had the most explosive December 25 and 26 in eMusic history, doubling our projections and blowing away our numbers," said David Pakman, president and CEO of eMusic.

"eMusic has entered a new phase of growth and as we continue to build and develop the number one site for discovering music and literature there will be much for our customers to look forward to."
