Apple iTunes Unlimited - an all-you-can-eat music subscription service - could be available as early as next month, according to report.

These moves were originally predicted in March, when the Financial Times reported Apple to be in the negotiation with music labels in order to offer iTunes users full access to music at a flat rate.

Now it appears Apple's preparing to launch the service in the US and has negotiated rights to offer half its current music catalogue through the iTunes Unlimited service.

The subscription service will be available through iTunes and also sold as a retail box, similar to the way in which MobileMe is sold. A year's subscription will cost $129.99 on its own, $179.99 with MobileMe or $99.99 for existing MobileMe subscribers.

MacDailyNews claims a late September announcement with late October introduction of the purported service, which will offer music in 256k quality - the highest quality digital music subscription service ever. Users of the service will be able to download whichever tracks they like, and will be given the option to buy music also.
