lulz, I feel like I'm just picking the ones that have this question and like, pasting my reply Hope this helps!
Here is a step by step picture tutorial :
Step 1-Up thar in the top right corner, type in what artist you want (1). Or you can click "Music" at the top black bar, and then when scroll down to whatever genre you want (2).
Step 2-If you did the genre version, on the right sidebar area, there should be a "Top songs", click that, and there, you can sort however you want. It works like normal. Idk why.
If you searched artist, however, you can't just click "songs" or "see all" at the songs slidey area (really, anything you see at the top right side bar, don't click it, it won't let you sort because it's a search result list. IDK why Apple did this, but it did )
You have to click the artist's name, under the top part of the right sidebar, where it says "Artists and More" (SEE BELOW)
Once you click that, the artist page pops up:
There, click "see all" for songs:
And then you can sort.
I hope that helped!
LOL sorry, I just realized that I changed artists halfway. haha....^.^"
