In one single afternoon Amazon Music served up loads of niche old favourites I had not thought to search for, introduced me to a couple of artists I would not have known existed otherwise, and probably rescued my failing love of music.
I now play a game with it and pick somewhat diametrically opposed aspects of my music tastes in quick succession— Superorganism, Cardiacs, Gavin Bryars, Nanci Griffith, Vivaldi, Anouskha Shankar, say — and then see what it comes up with. Invariably one of the recommendations will be something I already adore and one will change my life.
I stumbled into the Chris Thile multiverse this way, for instance.
Also, the company has a pretty terrible leadership: https://www.latimes.com/entertainment-arts/music/story/2025-...
I never listen to basically anything spotify recommends me, just songs from bands I already know and love. And if I were to purchase the whole discography of the breadth of music I listen to it would cost the down payment on my house
