2012 is going to be a landmark year for streaming music services in Australia. We've already got Rdio, JB Hi-Fi, Samsung Music Hub and Music Unlimited, and from early next week we'll have details on the big fish in the streaming pond: Spotify. We've known Spotify was coming for some time, given that it advertised for staff from late last year. It's now set to make an announcement next week on its Australian launch. That doesn't mean it'll launch next week, but the fact that it's alerted media to the fact undoubtedly means it won't be long before Spotify will be jousting with the established music streaming services already in Australia.
