The boys of INFINITE are scheduled to release mini-album titled 'Evolution' on January 6th but ahead of this, they've released the track '????.. (Voice Of My Heart)' for digital download on the various Korean music portals. The track is a beautiful ballad and is supposedly the title track from the mini-album. Infinite member Hoya recently mentioned that the rap portion of the song was written by himself, which shows off his multifaceted talents. Check out the track below and remember to support them by purchasing the music. [Thanks to everyone who sent this in.]
