I saw that a few people have received a shortened Music Season instead of the full Bubblegum Season. I've only seen one of the new Music Season levels, and it involves destroying color clusters, clearing licorice swirls, and completing rainbow rapids paths. There's a lot more to do compared to last year's Music Season.
What do these new Music Season levels look like, and how difficult are they? I can't answer this question myself because I don't have Music Season. (I don't have Bubblegum Season either for that matter.)
