Really bad. I buy a song, and then I can't find it. I feel like I lost a lot of mp3s which I bought over the years years ago - they expired or something- which shouldn't happen when I pay for something. The interface is very busy and tries to suggest a lot of things to me that I don't want. When I like a song, I buy the mp3, from Amazon digital music, and I want to be able to play it. Amazon store pushes you into using Amazon Music and it's very cluttered colorful, suggesting and thwarts you
