Amazon has gone down the shitter in more ways than one, but back in the day, circa 2005, I remember being downright amazed by their recommendation engine for music.

After a while I got into the habit of simply buying random stuff I've never heard of just based on their recommendation, and I don't recall a single instance when I regretted it.
