Having a music service seems to be all the rage these days. Sure we’re a little biased, we’re Zune users, but lately it seems everyone wants to be the new iTunes replacement. In the last six months Amazon, Apple, Google, Sony,  and Spotify have all made plays at being part of what comes beyond buying your music one song at a time. This is exciting, and makes it a wonderful time to be a music fanatic, but is it a wonderful time to be a company providing one of these services? Do any of these services actually make money?  Better yet has any of these services managed to change the way the you enjoy music?  Leave your thoughts in the comments.
