Music is quite literally the universal language. It brings people together, and allows now only the musician to express themselves, but also the listener. Music can be completely in a foreign language, but we listen, and can love it because the rythem and the beat are universal, and can be subject to interpretation. The same music can mean different things to many different people.
Many sites out there, myspace music, itunes, indaba and more, have developed successful music sites. But they have dropped the ball in numerous areas. And are not doing the musically inclinded or the musically interested justice.
