Downloaded and installed Twonky Music on my Motorola Photon today. I am able to beam music to my Airport Express, but the music plays a little faster than it should. I didn't see any settings in Twonky Music that look like they may be related. When I play music from my Mac Mini through my Aiport Express, it plays fine. So, I don't think the issue is in the Airport Express. If the music played at the right speed, this would be awesome. But it just doesn't sound right this way. It's close, but just a little fast so everything is higher pitched.
