Vaults gets classical with the pensive "One Day I'll Fly Away," Little Mix embraces passion in "Nothing Else Matters," and DNCE strings together more retro-pop riffs for "Be Mean" in singles this week.

Though its lighthearted pop sounds seem to clash with the video's visually sultry attitude, DNCE suceeds in making a titillating accompaniment for a song that makes being cool and sexy look easy.
