We redesigned the UI of M.net Music, the streaming service app from music entertainment channel M.net, to improve both music information delivery and overall usability. The new design elevated the visibility of album and chart information, as well as the “Music Styler” feature, encouraging greater user engagement. Transitioning from the previous dark gray theme to a white-based palette created a fresher, more inviting atmosphere. Adopting a flat design preserved simplicity, while adjusting icon sizes and enlarging touch areas minimized operational errors and enhanced user comfort.
