Scale is a tweak launched last night in Cydia, and with its help you can announce to the whole world about the songs you are listening to through the Music application in iOS. The tweak adds a button to the Music application interface through which you can share via email, iMessage, Twitter or Facebook the name of the song played by the application and the name of the artist who sings it. If these options are not really that interesting for you, then you have the possibility to add the name of the song to a playlist, so you can also make lists of your favorite songs.
Easily share what you're playing in Music via Twitter, Facebook, email, or message using Scale. When listening to a song in Now Playing, tap the Share button to find a variety of options. Add a song directly to a playlist by tapping the "Add to playlist" option. Facebook sharing is available on iOS 6 only.
Scale is available in Cydia's BigBoss repo, but only on iOS 6 you can use the Facebook Share function.
