Let's Sing 2021 is a new iteration of the musical arcade series Let's Sing 2020, recognized by many critics and becoming quite successful after the previous installments. The tracklist has been updated with modern hits as well as timeless classics. The main innovation is the "Legend" mode, where you will face off against computer players — avatars. There will be 16 of them in total, and each will offer up to three challenges. If you beat them, you will unlock the final boss battle, and by defeating the boss, you will firmly prove your talent.
