This is a free app I'm doing in free time after work. It can stream music from your android device (mp3, m4a, whatever) to you PC or Mac. You will connect to android via a web browser, browse music collection, search it, and listen from a browser. The reason I did it - hate sync, want to store all my music on Android phone and whenever I need to listen it from a PC - connect via browser. In a next version I'm planning to add music upload to Android device via drag'n'drop from a laptop. Download also. Check it out and enjoy, will stay free forever (there is an ad at the top, but you can turn it off in settings): https://market.android.com/details?id=uk.co.aloneguid.todash What do you think?
