How Spotify knows what music you like (hint: with machine learning)

Just two decades ago, if you wanted to discover new artists and bands to listen to, you had to go to to your local music store to rummage through the heaps of CDs or wait for your favourite music TV show to start. With the rise of the internet, you spent hours searching, downloading songs and meticulously creating your dance summer hits playlists. But today we like to get our music just like all other information – with one touch or click. You just tap your Spotify app and dive in the endless choice of tracks. Spotify has revolutionised the way we discover music in the digital era.
