Gotta Knock A Little Harder Lyrics

A friend shared this with me today and I gave it another listen tonight.
I like that the speaker's success or failure is left open-ended, a nice touch for story's sake.
I hear the repetition at the tail and interpret the call to "break down the door" as having double meaning ( my forte ). In one case the speaker is addressing his or her self (or others in similar circumstances) to break down their own barriers. It is a mandate of self-determination.
The other interpretation is that it is a plea to others. The speaker has reached out for the first time and is asking for help from outside,only now realizing that the task is impossible on their own. They are asking others to not give up on them, even in the face of the enormity of the task ( breaking through to that long sealed room behind the door ). Perhaps the change in the final verse is the breaking point, turning that energy from within to without, breaking down and asking for help from outside. "break through" is repeated, but eh single "break down the door"? "Breaking down" a door is a violent act, a measure of last resort in an emergency (which this certainly is). In this aspect, in this potential interpretation, the vocalist's urgency serves to make this plea all the more heartbreaking. Powerful stuff, especially if you've ever found yourself isolated and discovered that you were the one who had locked the door.

I'm reminded of the titular idea in Pink Floyd's concept album, "The Wall". But, hoo-boy, that's another book.

My Interpretation

I just realized that I said the speaker was "breaking down" and asking for help in "breaking down" the door... christamighty. See? multiple meanings pursue me like a pack of black hounds. I can not shake them.

@warmPhase Sadly Once you're in that room you're never fully out of it even if you break down the door.
