Looking for an easy way to Tweet the current song you're playing from the Music Hub on your Windows Phone? NowPlaying might do the trick.
You can choose from various Tweet formats that highlight the song title, artist, album name and genre. You can even create your own Tweet format should the templates not suit your fancy.
There is a trial version available with no limits on the tweets you send. But the trial version does limit you to only one custom Tweet Format. The full version runs $.99.
You can find NowPlaying here (opens Zune) at the Marketplace.
