It was lyrically appropriate of iTunes to pair the Genesis track, "It's Gonna Get Better," with "When You're Gone" by Amanda Shires this morning. "It's Gonna Get Better" cautions that a healing path might be a long one, and "When You're Gone" reinforces this outlook by suggesting that things will be better once you get past a particular obstacle.
While it would be more encouraging to hear that things will clear up immediately, it's often more realistic for them to improve eventually.
