The Ubuntu One Music Store in the Maverick Meerkat introduces a new ‘link share’ button to Rhythmbox.
When listening to a track you think the world should also be toe-tapping alone to just hit the ‘Link Share’ button in the toolbar to perform a quick search for the track in the 7 Digital catalogue.
One caveat with this pretty nifty treat is the requirement for the person viewing your link, and particularly in wishing to purchase via it, to be running Ubuntu and using the Ubuntu One Music Store.
