OK , as music lover (mostly as listener ) i developed weird abstract product that collect music recommendations from your Facebook friends and groups into private database , and in real time and let you play it ( you tube streaming ) its GUI sucks and its desktop app. but from programmer point of view it is doing its job and there are few weird people that like it : http://www.tunesamp.com/ hu .. and i very open to suggestion how to develop it or which direction to take it
