Hey DJ! for Windows Phone is a hands-free music player that allows you to play music in your collection using your voice. All you need to do is say the name of the song, artist, album, genre or the playlist you want to play.
The version 2.3 of the app just went live in the Store and as part of a New Year promotion, the full version is free until January 14.
