LEGO DUPLO is not a musical artist or band but rather a product line of the LEGO construction toy brand, aimed at young children. From the list of releases provided, which include words that translate to "nursery rhymes," "children's songs," and "lullabies" in various languages, it is likely that there is a confusion or an association with a series of music collections intended for children, possibly released by LEGO DUPLO or a related entity to complement the play experience with educational and entertaining music from different cultures. This aspect of the product could be an initiative to integrate music with play, enhancing cognitive and creative development in young children.

Since LEGO DUPLO is a brand rather than an individual musician or band, the concept behind these musical releases is likely tied to an educational approach, using universally familiar themes and tunes to engage young children. Each title signifies a collection of songs tailored to a specific language and cultural audience, demonstrating an inclusive approach to entertainment and learning. These collections might be used to engage kids in a multisensory play environment that combines the tactile stimulation of building with DUPLO bricks and the auditory stimulation of listening to music.
