Name that Tech Tune for a chance to win Startup BBQ tix

[Updated with answer and winners below]

The latest installment of our popular Name that Tech Tune contest offers a chance to win tickets to Startup BBQ, coming up on July 25 at Gas Works Park in Seattle.

Here’s how it works: To play along, listen below to the sound. If you think you know what it is, send an email with your answer to todd@geekwire.com. From the pool of correct answers, we’ll select two people at random to win tickets to the event.

We’ll notify the winners next week and give the answer on next week’s GeekWire radio show and podcast. In case you’re stumped, I gave a few clues during the segment in this week’s GeekWire show, as guest host Monica Guzman and guest Shauna Causey tried to guess the answer. Here’s that segment.

Good luck! Once again you think you know what it is, send an email with your answer to todd@geekwire.com. Regardless of whether you win, hope to see everyone at the Startup BBQ on July 25. (GeekWire is a media partner of the event.)

Update: Thursday, 7/14: The answer: Windows Live Messenger. We also accepted MSN Messenger.

Our two winners, drawn at random from the pool of correct answers: Rachel Radtke and Hector Gonzalez. We’ve notified them both so they can claim their tickets. Thanks to everyone who played, and we’ll have another one next week.
