FrostWire

FrostWire lets you send large files and folders over the internet for free and, at the same time, supports BitTorrent features as any other file-sharing application. The program is compatible with iTunes and has SoundCloud access to the largest community of artists and podcasters on the web. Whereas entirely free and open for improvements of its source code, it cuts out all spyware and crappy adware that may clog your computer.
