As far as I know these guys were never meant to be great singers but a fun group. Some of them even joked with that. They have good characters and are funny people. You can always sell a TV show with them (including the other two guys not present on this show). Also they are good actors, they played in good movies and good TV-dramas.
So it was definitely a good promotion for Scandal and I agree about the 4th song.
