This app is amazing, just like when you use it online. Spotify have now made this app free for Amazon users as well, the only down side is that you need WiFi to listen to songs (unless you have a premium account)
This Spotify app does exactly what you expect it to do. The design is just like the ones on the Smartphones, which looks clean and neat. Other than that, this app works perfectly on my Kindle Fire, and I highly recommend it!
I chose a hi rating as this app allows me to just pick a genre or decade and listen to that music. Given that it's random tracks I am listening to tracks that I am enjoying yet probably wouldn't jump to choose. Really like it.
