Entry for this week's contest. Song is "Go" by Lemaitre
The green is a play on the title, as are the arrows, although the gradient on them represents the way the song "ramps up". The splotchy rounded rectangles in the back are representative of the "base" of the song (I don't know music terms worth anything, so bare with me). The lines at the bottom are representative of the boops and such, particularly their sharpness. They're also reminiscent of fire, referencing some of the lyrics. I also shaped some of the blotches into a sort of billowing smoke to make the fire motif more blatant. The grids were inspired by the synth and the dither circle... things are the drums. Finally, the broken infinity is symbolic of impermanency, which I believe to be a theme of the song.
