I had two Echo Dots 2017/2018. I needed them to do two things: dimm/switch my lights in kitchen and living room and play music. The light thing worked 80% of the time, I'd say. The music thing never worked. I mainly listen to tango/vals/milonga from the 1930's to 1950's. Spotify has all of that stuff but Alexa is unable to find it. E.g. saying: "Play tango from D'Arienzo on Spotify" would yield Alexa playing some latin music, usually from the last 20 years. On Spotify. I mean it got that part right ... I never once managed to get it to play tango. After the light thing didn't improve notably over the course of those two years I sold the Dots end of 2018.
