Ubuntu 10.10 will make sharing your favourite tracks with all your friends and online buddies a breeze.
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. 
Once found you can hit the ‘tweet’ button to send your message directly to Gwibber or copy and paste the link to share via e-mail, blog posts or in instant messages. The link will open in a browser where a user can hit a ‘Get it’ button to preview and/or purchase the track and a ‘I have it’ button allows a mire some so-and-so the option to forgo the chance to expand their musical palette.
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.
