A 2008 entry into the Internet radio market, Sweden’s Spotify is offered on mobile devices, streaming boxes and PCs. It offers unlimited free, ad-based streaming (in the U.S. — it sets hourly limits in many other countries) as well as a paid premium services. Music can be purchased directly from online retailers.
Spotify claims 6 million paid users (prices vary by country and plan, but Spotify Premium costs $9.99 in the U.S.) and 24 million active users.
Under fire over royalties, Spotify announced in July that it had paid out more than $500 million to artists and was on track for hitting $1 billion by the end of 2013.
