For an upgrade with a fairly underwhelming number like 0.8.3 attached, the latest version of the Spotify desktop client brings the goods. First up is much requested the ability to create radio stations based on playlists or albums, with the click of a button (that would be the Start Playlist Radio or Start Album Radio button, for the record), generating a queue of similar music. A new boost to search brings up music in the main view when you hover over it in search results, while embedable HTML codes have been added to right click functionality. The service has also added Tumblr posting to the game. The update is rolling out today for Windows and Mac users
