Music streaming services

Posted on Updated on

Music streaming services like Beats, Deezer, Pandora, Rdio and Spotify have become a major form of music listening in recent years. People can use computers, phones and certain other devices to listen music of their selection, while a fast enough internet connection is needed. Streaming services often have a freemium business model, so that there is a limited service free of cost and a premium an account offering unlimited listening and other benefits. Subscription fees for premium services are usually around 10€ a month depending on service and regional location. This article concentrates on Spotify and Deezer as both are well known and have wide catalogues of over 30 million songs. The amount of African music available on both services is surprisingly good. Likes of Fela Kuti, Manu Dibango, Miriam Makeba, Franco, Angelique Kidjo, Salif Keita, Ali Farka Toure and Mahmoud Ahmed all have much of their discography on the catalogue. Similarly most recent hits by African artists are there. You may find them on Youtube too, which has wider and more global audience, but if you are interested in full albums and older music, counting on music streaming services is a better bet.

This includes almost the entire eastern coast of the Americas, a trail from Japan to New Zealand via Indonesia and Fiji, and a belt from Turkey to China, including Himalayas where the recent Nepal earthquake occurred.
