Cocomelon just phones it in. Almost all of their songs have some similar catchy intro leading into the song. Sometimes the intro is the same across different songs. Recently, my kid got into the song "Bicycle Built for Two (Daisy Bell)". I grew up listening to Disney Children's Favorites sung by Larry Groce, who sings it expressively and dynamically. Cocomelon's interpretation is just flat and conservative, as if it's a chore to get through.
