BSkyB, the British ISP, quietly launched Sky Songs a few weeks ago. Very quietly. The hybrid download store/streaming service is the first of many ISP-based music services to launch in the next year or so. By partnering with broadband providers, content creators will enter a new era and start to explore radically different ways of distributing and charging for their products.

But SkySongs has almost no buzz. To date, there has been a few online reviews. One was unfavorable while another was very positive even though it doesn’t leave the reader with the impression the reviewer actually spent time with the service. Nielsen’s BlogPulse has tracked 155 blog mentions of “Sky Songs” in the last five-plus months (and handful are not related to the music service). Quite a few of those mentions are merely references to Sky Songs in an article about competing services. And the vast majority of those blog mentions came before Sky Songs was released. In comparison, BlogPulse is tracking 27,570 mentions of Spotify and 6,327 mention of Imeem. Click here to see how the three search terms compare at Google Trends. (Sky Songs is barely visible.)

Nor is Twitter abuzz about Sky Songs. There have been a few dozen Tweets about Sky Songs in the last week. Compare the SkySongs silence versus the Twitter frenzy about Google’s music search news on Wednesday. During the press conference, which coincided with the news announcements, there were thousands of Tweets and re-Tweets about Google’s new music partnerships.

Looking at online activity can offer a good barometer of consumers’ interest in a product. After all, companies routinely follow online chatter to gauge effectiveness of campaigns, product rollouts and news releases. And Google can estimate the number of flu cases around the world based on volume of certain search terms. If BlogPulse, Google Trends and Twitter all show scant conversation about SkySongs from both media and individual sources, chances are consumers aren’t interested. Granted, the site just launched and BSkyB has much in store for marketing and promotion. But so little blog buzz is a bit alarming for a service that represents the future of music.
