Nice enough when it works, but quite a clunky functionality compared to Spotify. It may or may not load on your phone. I guess it depends on it's mood on that particular day. Quite annoying, actually, especially from a company such as Amazon. Great sound quality, again compared to Spotify. Good overall, but can often be pretty temperamental...again, compared to Spotify. Worth it for the 24bit file quality, especially if you have a decent pair of headphones/ear buds.
