How about doing to Music what we have done to Social Media. I am thinking of a GV Music where authors/editors can publish reviews for underground bands from their countries, not only reviews, but we can also integrate SoundCloud (or YouTube) in there and publish those music. I am focusing on underground music here, coz on one hand they need publicity, compared to mainstream music they are what blog are compared to MSM. Also, most probably those artists will be releasing their music under copyleftist licenses. We can also do interviews with musicians, compilation for new releases, etc.
Well, it’s just a crazy idea, but why not explore new fields we aren’t into and see how things will develop?
