Social music network MOG has announced plans to finally launch its long-promised streaming music service by the end of November, with all four majors plus indie aggregators on board. However, having originally said the service would be free and ad-supported, MOG has now decided to charge $5 a month for it. “We were exploring that model, but ultimately that model doesn’t work,” says CEO David Hyman. “None of these labels are doing it at a price point where you can offset it with ad dollars. It’s very simple economics. Even with an upsell to subscriptions, you just can’t make it work.” That provides context to the rumours that Spotify’s US launch won”t include a free ad-supported element – Hyman claims some labels are now refusing to license ANY free streaming service that”s ad-supported.
