Downloading songs from pay services over the internet generally costs 99 cents or more. But though the sites have licenses to sell the music, and a way to get it to customers, there have been too few customers so far. So one of the services is slashing its prices to 49 centers per track. That’s below cost, says the company – but you’ve got to get the customers somehow. Look for increasing competition in the next few months as more companies try to compete.
