Billy Currington’s sixth album capitalizes on the singer's easygoing charm with a string of warm-weather anthems and gorgeous ballads. Playful tunes like “Soundtrack” and “Do I Make You Wanna” inspire us to roll the windows down and turn the volume up, but it’s the bittersweet moments—like the stream-of-consciousness come-on of “Jonesin’”—that give Summer Forever a lasting glow.
