Hey DJ!, previously known as Speak To Play, is a Windows Phone app that enables users to tap a button to speak, and state clearly an <artist>, <song>, <playlist> or <genre> and the app will start up whatever matches in your music collection. Sounds pretty neat already, right? We previously covered the app when it was rebranded, was updated with new features and had its price tag slashed.

Now we're excited to report that Hey DJ! has been bumped to version 1.8 and is now completely free for the next 72 hours (until July 31st). So if you haven't already purchased a copy for your Windows Phone, you'll want to do so now while it's on offer. Once the period has closed, the pricing will return to $0.99.
