A friend of mine works in an office where, occasionally, when a co-worker gets up from his desk and leaves iTunes open, someone will walk over to his desk and loudly announce, "So-and-so is listening to [insert embarrassing music selection here.]" Now there's a not-so-secret program that broadcasts your listening preferences to your entire followers list. A new download for Mac users, Twunes combines music and Twitter. Twunes will tweet your current iTunes track, artist, and album with the ability to hashtag artists' names or add the #nowplaying tag. You can also add the #fb hashtag to cross-post to Facebook.
It's a fun way to discover friends' new music and to satisfy the curiosity of what, exactly, your co-worker is dancing to in her seat. It's not so good for keeping your Lady Gaga obsession a secret.
