This song is called “Trapt Door” on their 2007 album (Dreaming Out Loud) and “Trap Door” on the 2009 album. (Waking Up.) Both are bonus releases, and both are the same song.

Ryan Tedder often approaches songwriting from the perspective of being in a position to offer advice or help to the one he’s speaking with. Songs like “All Fall Down,” “Say (All I Need),” “Someone To Save You,” and “Something’s Not Right Here” fall into this category – coincidentally, these are all from the Dreaming Out Loud album. This song also is in this group, as Ryan is offering his listener a break from her false friends and overcomplicated relationships.

The idea of a trap door is that of an escape route, a secret exit from difficulty that leads to another place.
The Trojan horse draws from the ancient Greek myth of Helen of Troy; after a long and unsuccessful war, the invading army pretended to leave, but they were really hidden inside a giant wooden horse which was left behind. When the townspeople brought the horse within the walls of the city, they unwittingly brought in the enemy soldiers inside it.
The modern definition of a Trojan horse is “ any trick or stratagem that causes a target to invite a foe into a securely protected bastion or place.” (Wikipedia)
