Music players have, in the past, had some pretty awful designs. Some of the custom skins for winamp were impressive, but very difficult to use.
There seems to be a relatively common interface nowadays and I haven't tried to reinvent the wheel with this. I wanted to see how this worked with small control buttons; it gives a lot of breathing room to the design but it does make it more difficult to use. In retrospect I don't think it's worth making such a sacrifice where there's such a practical use case.
I benefited from going for a minimal design, without listing tracks or any kind of menus or volume controls. Most people don't have those advantages in actual software but in this case, it's nice to see how a very are design can look.
