There are lots of apps out there that use the local network trick to facilitate data transfer. You may have your favorite, but there’s always room for another. Music Drop, made by Codeceptive Studios, is a relatively new app that received a necessary bug fix update today. It’s a neat app if only because of its laser-like focus: send music from your PC to your Windows Phone.
Music Drop is simple enough. You launch it and it generates a specific URL, which you then type in your desktop browser (HTML5). From there, a Music Drop page is generated where you can simply drag and drop music off of your computer. Those tunes then get sent to your phone and voila, you have music on your device without a wired file transfer.
