I wasnt expecting this app/service to be so good. Its simple, and gets it right. Like being able to seamlessly access your locally stored iTunes music and playlists. Things like that just show the correct attention to detail and user experience. -Edit- A couple days after writing the 5 star review above the app was updated. The unnecessary "offline mode" toggle was added to the side menu (the same functionality was present previously, and better implemented). Now there is a additional step to take every time I want to access my locally stored music. Pointless steps backward like this are the exact kind of bad UI that I was talking about when I praised Amazon above. Now I am worried about future updates; they may continue to make the app worse instead of improving it. - I’m thinking the addition of the unneeded toggle is an attempt to candidly annoy people into using the cloud storage more. Otherwise, the new toggle has been implemented by someone that has never used the app before, or they have some other issue. Either way, I have canceled my scheduled Prime payment, and will not use any services after the free 30 day trial. I don’t trust the app(s) to remain good for a year when this type of backward update has already hit.
