According to CNet sources, Apple will not be introducing an iTunes subscription service next week.According to the article, Apple simply has not acquired such licensing from music labels at this time.
The rumor was revived after a claimed transcript of events was broadcast to several sites. These supposed transcripts are easy to fake, however, and have never been found to be accurate.
