I just saw this change marked in my updates recently for Rhythmbox in Ubuntu 10.10 and thought I would share whats new so far!
The new “Get a link for the current song to the Ubuntu One Music Store” button is now present and functional in Rhythmbox for Ubuntu 10.10.
When you click on the “Get a link” button, you are prompted with a dialog that scans the online music store for a match and displays the result for you. The address to the song or album is automatically copied into the clipboard and is ready to paste!
This feature can be used to send a link of a favorite song to your friends, where they can purchase the track right away if they choose to. If you want to go even one step further, you can even tweet the link to your friends and followers!
As you can see, this new Tweet feature is built upon the tightly integrated Gwibber application. Though I haven’t tried this yet, it should be possible to post to other services such as Facebook if you have them enabled in Gwibber.
It appears that the whole “Social from the start” idea that was first started with Ubuntu 10.04 is now moving to another level and becoming commonly integrated with deeper parts of the operating system.
Above is an example of Twitter integration in the Ubuntu Software Center that allows you to easily suggest software to your friends.
