Are you using Google Music? The more important question is have you purchased music through Google Music? While there was quite an uproar to get Google Music Beta invites, and there was a large movement to upload songs to Google Music; there is concern that Google Music isn't living up to expectations. Cnet posted that Google is reporting that adaptation and revenue are well below expectations.
While it is fair to say that the service has not officially been released for even a quarter yet, there is still concern that the service isn't making any money, and there are still issues that need to ironed out.
Google has not done a whole lot of advertising for any of its products. Seeing a Google commercial is a rare treat, and in the last three months I only remember seeing a Chrome commercial and a few Google Plus commercials. For Music to take off, there needs to be a significant marketing push behind it. Also, there needs to be a better presence on desktops. While the web interface is easy to use once you find it, most people are programmed to open iTunes or Rdio to access music services.
It isn't fair to criticize Google right now when it seems like the Music Industry as a whole has no idea where it is headed. Is the future the old iTunes model where people buy music directly from one place, or is it Spotify, or Rdio, where one monthly fee allows access to virtually all music?
While Google Music still has paint drying inside the virtual storefront, there are concerns that need to be addressed. The idea of uploading personal libraries of music is an appealing one, and both Google Music and Amazon MP3 did the same thing at almost the same time. The difference is Amazon MP3 is more likely to put albums on sale for $5, and that's a bargain that's hard to pass up. So what's in store for Google right now? Google has not responded to CNet's request for comment, so things might not be as bad as we are lead to believe. The next 3 months are important though, there is no hiding that.
