Twunes... So you're a Twitter AND a music addict? Ever wanted to know what your ("I'm a Mac") Twitter buddies are listening to on iTunes? Always looking for musical inspiration to widen your musical horizon?

Well, good news: here's Twunes, my free Mac OS X application that tweets the current iTunes track's title, artist & optional album that you're listening to.

Key features include:

• You can hashtag the artist name so that it's clickable in Twitter clients and you can find other people tweeting about the artist you're listening to.
• You can add the hashtag #nowplaying.
• You can add the hashtag #fb to crosspost your tweet to Facebook, too!
• You can add an iTunes Music Store (iTMS) link for your song - if it's available. Twunes tries to find a match.
• The cover art of the currently playing song is shown if possible.
• You can choose whether to include the album name or not.
• As a convenience you can remotely control three key iTunes functions: play, pause and next track.
• Your Twitter credentials are stored safely in Mac OS X's Keychain.
• Twunes can optionally stay on top of all other windows.
