Digital Music Service Now On PSP

If you've recently downloaded the PSP's 6.35 update, you already have access to Sony's "cloud-based, digital music service."

In the recent software update, Sony added Music Unlimited powered by Qriocity under the music tab. It seems like the new music service isn't only limited to PSPs going forward. Here's a quote from the official website:

"The music you want, when you want it. Qriocity offers access to millions of songs on a variety of Sony devices. Upload your personal library for access anytime, anywhere or discover new favorites with automatic recommendations based on your unique listening habits."

Has anyone tinkered around with this yet? What are your impressions?
