The data collected by the company it manages Spotify they speak for themselves: the online platform that allows you to listen to your favorite music by choosing from 40 million songs is the most used by users. Monthly logins exceed 200 million active users each month. Success is largely dictated by the possibility of using the service for free. Listeners who prefer not to subscribe to a subscription plan are still the majority. 
At the moment the biggest earnings for Spotify they still come from advertisements in the free version of the app, while subscribers do not seem to have increased considerably, despite an increase in the use of the service. If 113 million people prefer to use the free features, 87 million have instead signed up for a monthly subscription, compared to 70 million subscribers last year. One of the causes of the recent increase in the use of the services of Spotify is to be sought by the recent success of products such as Amazon Echo, which lend themselves perfectly to music playback, thanks to the ease of use of these smart speakers.
