US streaming music service MOG has published some stats about its growth, although they’re not the most reliable indicator we’ve seen. The company cites Quantcast figures claiming the MOG Music Network now has 13.2 million monthly unique visitors in the US, and 23.7 million worldwide. The unreliability? This is for the entire network, which includes the MOG music service, but also its network of thousands of music blogs. In other words, there’s no proof that all those millions of people are using the MOG music service, which is subscription based. Even so, based on the figures, MOG says it’s now the ninth largest music portal.
