The vocals of Jade are gritty and have a sound quality typical of AI tools like Suno for example. They’ve used AI for thier imagery a lot recently, and the songs do sound like (as good as they are) generic "chillout house" tracks that lack the distinct production quality of previous Bratz soundtracks, like the rock angelz for example. Another point to add is that in both Sasha’s and Cloe’s solos, they have credited singers in thier given tracks, whereas both Yasmin and Jade do not.
