Apple watch series 3

I want to purchase an apple watch but the series 5 is too expansive. I want to know if the series 3 can allow me to listen to my Spotify playlists and track my workouts if I leave my phone at home or in the car. I also use the peloton app's audio outdoor running workouts and want to know if I can continue to use that with the series 3 apple watch. Please help me answer some of these questions. Thanks.
