Let's Sing 2021 works as a party game, if everyone in your party has the same music taste and likes newer pop songs or if you like to set up your friends to fail. However, the lack of diversity in the playlist and the requirement to sing songs that you don't know to play many of the modes make this a less than ideal game for people outside of its target audience. The core idea is solid, but the weakness of the note charts and short song list make this a hard sell for me. I would like to see a themed version of this game with more accessible songs, for instance, something like Let's Sing: The 80s. However, as it is, I can't recommend this game outside of a narrow audience.
