yTunes was recently featured on the Italian reviews website melamorsicata.it. While my Itallian isn't that good (neither is the Google translator's apparently) the article points out that the Internet community is awaiting the arrival of the iTunes cloud. If Apple does what we are expecting them to do, other competing services such as Pandora will be forced to do so.
However given Apple's vested interest in digital rights management this obviously is not going to be a free or "all you can eat" service. The article then goes on to point out that YouTube is one possible solution for free streaming music, but can be a little clumsy if you are using it for large volumes of content. As if you didn't see this coming; the article finally points out that yTunes offers a solution to all of this right now, for free!
Thanks for the great review melamorsicata.it!
