Celltrac Software is working on the Windows Phone App CloudMusic, a SkyDrive music app, and is looking for a few beta testers. The application taps into your SkyDrive account and allows you to play any music files that you have stored in the cloud.
We've gotten a sneak peak at CloudMusic and the app is laid out in simple fashion with pages for your SkyDrive music collection, what is now playing, recently played songs, and new songs. The app does require you to organize your music in a specific manner in order for CloudMusic to find the tunes.
Just tinkering with the Beta, it does have room for improvement but a nice step in the right direction. Songs took a while to load and you've got to get the music file organization just right. If you're interested in being a beta tester for CloudMusic just email your Windows Live ID to email@example.com.
