What i wanted to add with that shirt was that

What if this app could act like a graphical equalizer detecting music being played with the built in media player and then the left leds would work based on the bass, the middle on the vocals and the right ones on treble.

If that is too much work then just work like the Knight rider (or some other pattern) to any media being played and it would just detect music being played just like Tune Wiki does
