Why does iTunes only play one song? So here's what my iTunes looks like right now:



Nothing on this screen does what I'd expect, which may or may not be a problem with my expectations.


Why does double clicking on a track play only that track and then stop, rather than playing the album from there?
Why does clicking the play button next to "Demon Days" do nothing? What is the button for?
Why does clicking the arrow icon to the right of "Demon Days" and then choosing "Add to Up Next" add nothing to Up Next?


Can't make head nor tail of iTunes these days. Am I just getting old?
For some reason your songs are greyed out. That's why it doesn't work a you expect it. 

Try following : Select all these songs then under right mouse click => Check selection.
