Benefits / Improvements
Honestly i'm not that interested in this app UI . that's why i choose to redesign the UI instead of logo.
i make improvement/benefits to the app UI by add more feature such as soundcloud (direct link to the particular song) so user can also sync with their account or at least find simillar genre to the music they loved on soundcloud(internet) and also user can change the background and thumbnail picture in now playing ui.

I Do not really understand how to proof it. but you can check all detail and find out for yourself.also you can ask anything about the design in the comment section,perhaps it will help proof ;)
