Trackball MP3 Player: innovation from past interfaces

We all know how successful the Apple iPod became which was in part to its cool click wheel, not here is another MP3 player trying something different.

This new MP3 player is just a concept, but if it ever reaches production it will allow the user to change the music and the volume by rolling the trackball.

Now a trackball is old tech but being used on an MP3 player is a little different to what most music lover’s use.

Not that this feature will be handy, but I like the idea of being able to turn this player upside down on a table and then change music just by rolling it on the table (maybe that will get boring quick).

One problem with concepts is that most never make it to the real world, what do you think of this design?
