‘The Twilight Saga: Breaking Dawn – Part 2 Original Motion Picture Soundtrack’ Various

It’s a sad goodbye from “The Twilight Saga,” which sees its last installment, “Breaking Dawn – Part 2,” hit the big screen this week.

The soundtrack ’s melancholy lingers over the sound like dust over old boxes of family photos. Yet it’s focused on delivering a soulful sound that is neither too arcane nor too mainstream.

Nikki Reed, who plays Rosalie Hale in the film, appears on the piano ballad “All I’ve Ever Needed,” alongside husband and former “American Idol” contestant Paul McDonald. Green Day, the biggest act on the soundtrack, is bland on “Forgotten.”
