You think this is bad? Try using Apple Music with a traditional mouse. You can’t even right click on half of the interface, dragging elements near to scrollable edges doesn’t trigger any scroll, and UI elements like the star on favourited songs just don’t show up. It’s marginally better on a trackpad.
Try dragging a playlist around in the left-hand sidebar such that scrolling is required. Or scrolling with horizontally where holding down shift is usually required.
