Tweet This Song! is a simple Windows Phone app, enabling users to tweet a song that's currently being played to the popular social network. The tweet contains details including an Xbox Music deeplink. Time spent within the app itself is minimal. The app was recently bumped to version 1.4 which introduced Windows Phone 8 support.
As well as this update, the pricing for Tweet This Song! has been slashed and can now be picked up for free. This is without advertisements of any kind too. It's a sweet little app that offers a unique experience for those who wish to let everyone in on what they're currently listening too.
