Following last year's release of "Lotus," Christina Aguilera is back with a mid-tempo ballad that will highlight "The Hunger Games: Catching Fire," one of the biggest film releases of the year. "We Remain" finds Aguilera delving into thoughtful songwriting and channeling Katniss Everdeen when she sings, "Whatever happens here… we remain."
Taylor Swift -- who happened to contribute a single to the last "Hunger Games" soundtrack -- has returned from her "Red" run with "Sweeter Than Fiction," from the new British film "One Chance." The bouncy love song was co-written with fun.'s Jack Antonoff and features some of Swift's most straightforward pop riffs to date.
