Updated below with answer and winner.

Our Name that Tech Tune contest returns this week on the GeekWire radio show and podcast, with a chance to win a Swingbyte golf swing analyzer, courtesy of AT&T.

This gadget attaches to a golf club and works in conjunction with a mobile app for Android or iPhone to analyze your golf swing in real time. Online analytics are also available. The device normally retails for $149.99. We’ll be giving away one Swingbyte to one winner chosen at random from all of the correct answers to this week’s challenge.

We’ll accept submissions through Wednesday, Aug. 1, and name the winner next weekend.

Are you ready? Here’s the tune.
