Farewell Song / Ken Hirai & Masamune Kusano (SPITZ) Cover

I’ve never heard a song so deranged in its despair over being dumped by a lover.

And yet, within the madness of these lyrics, I feel a sense of beauty.

I can’t help but hope that the protagonist of this song gets along with the next person they’re with and finds release from their loneliness.
