the great thing about spotify is its discovery algorithm--it's uncanny how accurate its recommendations are. amazon's is primitive in comparison, although i notice it gets a little better the more i listen to the app. also, whereas spotify has radio stations for every artist, amazon has very limited stations. amazon does sound better, but at the end of the trial period, it may come down to how hard i want to work at setting up my play queue.
speaking of which, is there a function on amazon which continues to play similar songs after a queue is finished?
