I knew the putpat.tv app already from my SmartTV and from the mobile phone. But they lacked FireTV me since I expected that because of the strong hardware everything would run smoothly (in SmartTV not) - and it is! Then I hear a lot and a lot of music - and what is not mainstream - I have a lot of fun with the app. Just pretend in their own settings some bands or musical styles and weights and even comes almost only what you want to hear. If this is not so, you can mark during playback individual songs also, so that they will no longer be played, and if anything exactly meets the taste that more similar songs are played. This all works very well and also has the ability to create playlists, or search specifically for individual songs. The short commercials come after 3 songs, but when you hear more, also after a while no longer :-) I have nothing negative to now (about six hours with FireTV and APP): art, music selection, functionality - everything is perfect, so I'm happy and awarded five stars can!
