Apple released Match iTunes service, but was delayed two weeks.
The service, which costs $ 25 annual subscription, promises to recognize all the songs in a person's computer and stored in an online account on distant servers known as the "cloud."
Songs can be downloaded or sent to another Apple device without the need to physically connect to the computer.
The songs are not recognized computer can be loaded automatically. The service ensures that work with multiple computers used by the same person without duplication.
Apple Inc. declined to comment on the launch delay. He had previously said would be available to Match iTunes in late October.
A previous message in iTunes saying that the new accounts would not be accepted was published in error and was removed.
