iOS: AirPlay is great if you have a Mac or an AppleTV, but if you want your iPhone's music on other devices you're out of luck. AirMusic solves that problem by serving up your iPhone's library on DLNA-compliant devices like the Xbox 360 and PS3, as well as some TVs and set top boxes. You can even stream to Windows Media Player.
On the first launch, AirMusic will need to scan your iPod library but then it just takes a few taps to set up. First you need to turn on AirMusic, which will prompt it to start looking for connections. Then you head over to your DLNA device (in my case, an Xbox 360), go to your Music Library, and choose your iPhone from the list. It'll be labelled as "AirMusic: ". Select it and you'll see the connection appear on your iPhone. It'll even know what's connected. Now you can browse for the song(s) you want using your own playlists or any standard options (like by artist, album, etc.) and you'll be playing your music in a few seconds.
AirMusic is incredibly easy to set up and use and works very well. It'll set you back $2.99, but it's worth it if you want to stream music, hassle-free, from your iPhone, iPod touch or iPad.
