Now that the dust's settling in the wake of Nokia's Loudeye acquisition, Sony Ericsson reckons it's time to get down to business on their own direct-to-phone music downloads. The service (which they've previously alluded to) will be called M-BUZZ and will use its PlayNow service -- currently focused mainly on ringtones and games -- to get content onto the Walkman phone of your choice. Actually, that's not quite true: M-BUZZ will initially be rockin' only on the W850 and W950 series; not quite the sweeping, retroactive compatibility we'd have liked to see, but with the W950's generous legroom for tunes, we do think they picked the right launch phone. Sony Ericsson's saying they'll be first focusing on "new and up-and-coming artists" out of Sony / ATV's library (read: crap they can't find any other way to sell?), but they seem to be leaving themselves the option of significantly expanding the catalog if the service takes off.
