4. Latvia - Cosmos: "I Hear Your Heart"

Cosmos is an a cappella group. Unlike the other numbers so far (and indeed, likely for the rest of the night), they're clearly singing live. All the signs of good a cappella are here: tight harmonies, smooth beat boxing, lame choreography, a constipated-sounding tenor singer. Unlike most a cappella groups, Cosmos has a small metal puppet. The puppet is so lame, I stopped listening to the song and tried to figure out why they needed the prop.
