Lyric discussion by mmparker178 

I think its a song could be interpreted in many ways but it made me think of it as a metaphor for the rich 1% of the world keeping small children in factories so that they can enjoy good for cheap. The small children being the big birds ( big birds meaning could have big futures) in a small cage ( in the factories that control their lives ) and the sad song they sing that the 1% enjoys being the goods that are sold for cheap because of child labor.

Another interpretation I think of is of a free-spirited child being trapped in a very controlled environment. The free spirit being the large bird (big personality, bright future and large imagination) being trapped in a small cage ( or a small town where they are not challenged or have very controlling parents who do not encourage their free-spiritedness) The lovely song the free spirit sings is the song that their parents and their peers wish them to sing. They are trapped because of where they grow up.
