Turns out there's 15 songs like that and they all have "Extended" versions. And all of them have been released on Youtube.

Just go to "Load videos" and it should show up relatively quickly. The only ones that don't load up are Just The Way You Are, Aerodynamic, and Celebration, unfortunately. Thankfully, there's another video of Celebration and it is so wonderful.
