'The [former Spotify] employee explained that, "the vast majority of music listeners, they're not really interested in listening to music per se. They just need a soundtrack to a moment in their day."'

Music changed as a response to this:

'Songs got shorter, albums got longer, and intros went away. The hook got pushed to the front of the song to try to grab listeners' attention immediately, and things like guitar solos all but disappeared from pop music. The palette of sounds artists pulled from got smaller, arrangements became more simplified, pop music flattened.'
