Spotify’s integration with Facebook is pretty cool—it’s great to be able to automatically share songs and playlists with friends—except, of course, when a guilty pleasure’s making its way through the queue. Apptrocity’s new Mac app Twitify ($1) gives Twitter users a similar sharing option, and throws in support for iTunes as well. Whenever you listen to a song, it’ll automatically tweet out to your followers, so it’s time to start building some respectable playlists. 

If you’re concerned about overwhelming your friends’ feeds, Twitify’s preference panel includes the ability to tweet at intervals of five, ten, or fifteen songs rather than every track. We’d recommend one of these options, otherwise you may just see your follower count drop. The app is worth the buck for music fans, and Apptrocity is promising a “mega” update in the coming days with a refined UI, custom tweets, a feature it’s calling “smart detection,” and more.
