One of the features that was talked about and proposed a few months back was a music store for Ubuntu where one could easily purchase music and somewhat fits in with Canonical's plans for the Ubuntu Software Store (or the "Ubuntu Software Center" as it's now called). Plans were laid out for an Ubuntu One Music Store and the first packages to support this in Ubuntu 10.04 LTS are now available.
The Lucid specifications for the Ubuntu One Music Store on the Ubuntu Wiki mention "The Lucid music store project aims to deliver the ability to purchase music from within a desktop music player. The overriding requirement of the project is to minimize engineering effort. This will be achieved through the usage of off the shelf solutions with minimal modifications. Only changes classified as blockers will fall within scope of this project. No effort will be expended towards improving the user experience of the default off the shelf components."
