I've been listening to japanese music for a long time now, and I've noticed that a noteworthy number of emotionally charged songs reference the sky and/or the clouds as part of a metaphor to express regret or loss or something like that.
Is this just a convenient metaphor? Is it an extension of the traditional use of seasons to convey deeper meanings? Is there a body of famous poetry or something that established this lyrical trope? Or am I seeing a pattern that is just a consequence of the selection of songs I happen to have come across?
