When it comes to the world's single biggest music subscription service Spotify, changes such as opening up to the USA after 2 years of preparation don't come easy - but what they'll reveal this Wednesday may well change their whole outlook by opening up to 3rd party developers. Spotify recently sent out a message that they'd be having a press conference this week, and as All Things D's Peter Kafka notes, the change they'll be revealing more than likely has more to do with how their music is delivered to you, the consumer, than it does with what music and services they'll be providing. It does make sense that they'd be connecting with more services, as their recent deal with Facebook has proven to be more than lucrative for them already. What does this mean for you, the Spotify free service user? Not a whole lot. How about you the Spotify Premium user? Perhaps a new collection of options for places of access!
