Hoshino Gen will digitally release his new song "Souzou" on February 17.
This song was created as the 35th anniversary theme song for Nintendo's 'Super Mario Brothers,' and its TV CM, starring Hoshino himself had been airing since fall. On the song, he commented, "It's been awhile since I spent so much time working on a song. I incorporated my feelings toward 'making something' into the sound and lyrics. In addition, I added my respect toward Mario and Nintendo."
