You can always get what you want… on the new streaming services – Telegraph

Recommendation and discovery of music is the next frontier. Some services, like Beats Music, have developed secret algorithms, using smart data from social networks to produce automatic playlists. Others use a mixture of hand-built categorisation and automation. Pandora is the American market leader in computer-generated playlists. Users plug in a song they really like and, via its “music genome” system, the service generates an endless stream of similar sounding recordings. – Jeremy Silver, The Telegraph
