The accessibility for this design is pretty terrible. There's a reason the gold standard for closed captions is still white text with solid black background. That way, regardless of what's going on in the background, the text is still readable for someone with poor eyesight.

Out of curiosity, I used this site [1] to get the contrast of some text, specifically the artist name on the Apple Music now playing bar (in the "Updated App Design" part of the page). During parts of the video, the contrast of the artist name with the background was 1.7:1, which is terrible. For reference, the minimum recommended contrast by WebAIM is 4.5:1 [2].

Maybe there are accessibility options that improve things, but the defaults seem terrible. The goal for any design should be reasonably accessible as default, with robust options for people with more specific needs. As it stands, this UI is just too hard to read, and Apple needs to make a second pass.
