The key ambition of this project was to create a set of icons that gave way to the music. Icons, which sat back and allowed the users content to take centre stage. Therefore all of the shapes were designed to be as light on the eye as possible and sit comfortably alongside the type at every size. A strict new grid and angle constraints were defined to ensure that every icon adhered to the same standards and style. Great care was also taken not to change familiar metaphors; only to enhance the experience where required. This is a set of icons designed with Spotify's millions of music subscribers front of mind. Four months in the making, six hundred crafted icons and over three years later, they are still working just as well as intended.
