Demandware says 30 of its clients booked more than $100 million in online sales in 2015, up from 22 a year earlier.
The digital music service will limit free streaming to 10 hours a month.
The service, which launched in United States last July after establishing itself in Europe, always acknowledged that the unlimited free streaming would expire after a limited period. However, only now, after the service has established itself via its stand-alone offering on consumer’s computers, as well as its social integration with Facebook, is Spotify beginning to impose the cap.
Once a consumer hits that cap he can pay $4.99 a month for unlimited ad-free streaming or $9.99 a month for unlimited ad-free streaming access to Spotify on his mobile device, as well as his computer.
