Speaking of The Beatles, you know the song You Won't See Me, from the album, Rubber Soul? That always struck me as an oddly upbeat setting of some very downbeat lyrics. Though the days are few/They're filled with tears/Since I lost you/It feels like years/Yes it seems so long/Girl since you've been gone/And I just can't go on/If you won't see me. This guy is almost suicidal, yet he's singing this bouncy little number.
