King of Mask Singer
If you like K-pop, I recommend (that) you to watch this show. All of the entries contestants wear a comical masks and sing a songs. Some of them are famous singers, and others are entertainers. You should guess who they are by listening to their songs. I don't know much about idols' songs and I don't watch Music shows at all. But I can enjoy this show because they sing not only the latest songs, but also old good old ones.
