Miley continually pushes her limits as much as our expectations with every release. This means you never quite know what you’re going to get, whether it’s a hip-hop/cabaret banger like “FU,” a narcotic dark-pop doozy like “Dooo It!”, or a sugary pop-punk sparkler like “He Could Be the One.” But the one thing that remains consistent is those powerful pipes, best highlighted on the romantic ballad “Stay.”
