In other sort of related music biz news, (which Bob Lefsetz has yet to complain about), Sony launched its new “unlimited” music service entitled Qriocity in the US today.

For $10 a month, Qriocity subscribers get access to music from fall four record labels and 6 million tracks. Music will be streamed from Sony’s servers to devices so users don’t have to worry about clogging hard drives and Sony won’t have to worry about building any complicated software platforms (we’ll get back to that). Qriocity scans a user’s hard drive and then provides access to songs from their media libraries, including Apple’s iTunes. [CNet.com]

Qriocity plays across a range of Sony devices, including the PlayStation3, Bravia TVs, Vaio PCs and Blu-ray Disc Home Theater systems (but not yet on the PSP). View a preview video of the Qriocity service after the jump.
