Yes, we're partnering with 7Digital.<p>We'll be looking to see if there are any simple changes we can make to the codec installation experience when mp3's are played the first time, but no major changes from how it works in Ubuntu 9.10.<p>Initially this will only work in Rythymbox, but we're making a GTK widget that should make it easy for other players to embed the music store as well. You can see up to the minute code here: <a href="https://edge.launchpad.net/libubuntuone" rel="nofollow">https://edge.launchpad.net/libubuntuone</a> and follow along with progress here: <a href="https://blueprints.edge.launchpad.net/ubuntu/+spec/lucid-ubuntu-one-musicstore" rel="nofollow">https://blueprints.edge.launchpad.net/ubuntu/+spec/lucid-ubu...</a> .<p>At the moment we've got music purchasing basically working and are cranking along on getting downloading finished, and building packages. Hopefully there will be something people can start playing with in the Alpha3 release of Ubuntu 10.04.
