For me, this song is all about the meaning of love that one person give for he or she with all of the heart. I choose this song because I think it has an important massage for someone who faces with separation immediately and has connotation in this song.
The songwriter start words with a feeling can’t believe and try to cover one's eyes and ears, doesn’t want to know anything. The words “The sun cannot fall from the sky” I think these mean the hope. The sun is the symbol of the light, there is no way to fallen from high sky down to the ground be compared as love, the more you love the more hurt you get. When he knows the person that he love already gone so it make painful and hope inside your own that would be any way to stay together.
This song repeat about the word “Tears of an angel”, it is the name of this song too and means the great loves even the angles in heaven also pity and sympathize with they love until cry. If you stay in that situation and the person who have left is the very important and you love very much. During that time you will feel like time stop and your world collapses in front of. But in fact, the more you cry is useless because natural will continue “The river would run to the sea”.
In short, the word in this song is sad but it isn’t that in future your life unhappy because “Every day hope will grow”. This words show me that the hope is still in every time if we don’t give up. Sometime it may fade and make you cry. You must walk forward; the disheartenment or weaknesses are usually happen to every human. No one can stand beside you forever.
So in my opinion, this song has the message to give people have positive outlook with positive outcomes, don’t bog in sorrow and keep the memories in the past that once we’ve loved each other very much. Love is always beautiful. Thanks for listening.
