Wow this latest version of iTunes reminds me how much it is an anachronism.  Before iPhones went total direct, you had to dock to get your music. And now with streaming music services, who ever needs a real MP3 anyway.
Plus the interface has gotten hard to figure out. For instance, I still have some old MP3s and I just wanted to sort the most recently added. Apparently, the upper left icon just shows the album view, you can't change it.
If you want to see your songs listed with all the fields, then the trick is to go down to the Playlist section on the right (and not the upper left stuff). Then to actually get to that view, this means you have to click on the lower recently added and then in the menu bar choose View/View As/Songs which will get you back to the tabular view.
