Spotify’s long-awaited    US debut is finally here. After nearly two years of broken promises    from Daniel Ek, the music service’s co-founder and chief, the popular site    is going live stateside later today. 
 However, the greater significance is that finally another European digital    service is going to try to break America. It’s like watching one of our    favourite bands trying to crack the US music market – we will them to    succeed but are not surprised when they regularly don’t.  
 Despite frequent protestations from European venture capitalists and    technology entrepreneurs, that this side of the pond is just as fertile for    amazing start-ups, the truth is that the vast majority of global digital    players are still American. 
 Apart from a few notable exceptions, Skype and Last.fm (which is now declining    in popularity in Europe as Spotify’s star continues to rise), very few    European digital companies really gain global popularity as stand-alone    consumer services. 
 Spotify’s launch has been eagerly awaited by early technology adopters in the    US. However, it is entering a crowded and well-established marketplace with    services like Rhapsody, Mog and Pandora, already occupying lots of mindshare    and music lovers’ time. 
Spotify Premium Usage Limit Question
RaphaelSamad Says
I am thinking about signing up for Spotify Premium.  However, I am struggling to find out what the usage limits are.
Can I, for example use Spotify Premium on my Iphone , my Android  and  one of my Daughters on her Mobile (Spotify do support it) -  and can we  then also use it on all our computers (though probably only a maximum of  2 simultaneously).  Also, for offline listening on our mobiles, can it  instead link in with Itunes or is it really better to use the Spotify  mobile application.
If we can, then sharing it with the family would definitely help to justify the price.
Also, are there any offers or anything for Premium Sign Up going around or it is just the normal £ 9.99 per month.

You can use it on as many devices as you want, but I think you'll find you can only use one at a time...
That's right, it detects if there are more than one app online at once
