Cupertino, Calif.-based Apple’s much rumored streaming music service, dubbed iCloud, will reportedly scan and mirror individual iTunes music collections on its servers.

Bloomberg BusinessWeek claims that intimate sources informed it that Apple has acquired new licenses for its potential iCloud service that will let the firm to scan and mirror iTunes libraries.

The report also claims that Apple will swap substandard music files stored on customers' hard drives with higher-quality files.

However, the potential streaming music service will not be free. Authors Brad Stone and Andy Fixmer wrote that the rumored service may be a huge shift, but it will not be free.

Last month, a separate report claimed that the iCloud service could be free to begin with, but would eventually require users to pay a fee.

Precise pricing details for the service are yet unclear, though Stone and Fixmer guess that Apple could bundle streaming music services into its revamp of MobileMe, which is available for $99 per year.

Fees for iCloud could also help labels extract some money from pirated music.
