You know, I agree with most of the sentiment here. It's not particularly great design. I see it, I understand it, but it's not, in my opinion, great design.
In fact, when I really stopped and though about it, the new Apple Music really reminds me of this:
Admittedly this isn't the best picture, but it highlights some of what I am referring to.
This was from Zune HD which came out in 2009. It's been almost 7 years, and Apple is now starting to borrow some of these ideas anyways.
Do I think Apple will go to tiles ever? Heck no, but this is where it starts.
After the Zune HD came out, and it was considered a popular interface because it was different interface. Microsoft then decided to go and turn out a Windows Phone OS based on it, and then eventually move it over to their desktop platform.
Anyways, those are my 2 cents.
