Is there any song that makes you depressed kinda?

Michael Buble - You don't know me. Actually, many of his somber songs including "try a little tenderness" really hit me hard with reality. There's this one girl that, for probably for more than one reason, I lost my opportunity to be with because I let her go and never really told her how I felt. And now almost every song by Buble reminds me how much I've loved and lost. His stuff is truly inspiring but he reminds me of how much pain love can be.
