Music is delight for the ears. That one can also recognize certain songs visually, and we do not mean the moving images of the music videos but in a simple graphic icon, that was the thought of the graphic designer Viktor Hertz of Sweden.
In simple graphical representation you can not only provide traffic and other information signs but also describe well-known favorite songs easily. So now let’s puzzle: who would know all the icons even without captions? In Hertz’s Flickr stream there are still many more songs to guess.
