First launched on non-mobile devices in February, "Music Unlimited Powered by Qriocity" will let PSP owners instantly stream songs, create playlists, and received personalized music channels from a catalog of "over seven million songs" from the Big Four music labels: Universal Music Group, Sony Music Entertainment, Warner Music Group and EMI Music, as well as independent labels and publishers.
Users will be able to play songs through most internet-connected Sony devices, like PlayStation 3 consoles, Bravia TVs, VAIO laptops, and Blu-ray players. PSP owners can access their accounts on the go. See Sony's video demo below.
Because playlists are stored remotely, in a "cloud," PSP users can synch their music folders to their PlayStations without having to transfer any music files.
Users can try a Premium account free for 30 days by going to Qmusic.
In March, Amazon launched a controversial cloud-based music locker, ignoring protests from record labels over Amazon's right to store digital music. At the time Sony said it was "keeping all our legal options open."
