Last week, Miley Cyrus dethroned Ariana Grande to take the Pop Clash title for 'Wrecking Ball.' Can she keep it this week as she faces off against Taylor Swift's 'Everything Has Changed'?

Miley shows her off her vulnerable side with 'Wrecking Ball.' Unlike the twerk-friendly 'We Can't Stop,' this power ballad is all about the slow, inevitable decline of a relationship. Whether or not it's rooted in Miley's personal life, it shows that she can put all of her emotions out to the world.

Taylor Swift is no stranger to wearing her heart on her sleeve and 'Everything Has Changed' is no exception. The Ed Sheeran collaboration celebrates the start of a relationship. With lines like, "And all I feel in my stomach is butterflies / The beautiful kind, making up for lost time, / Taking flight, making me feel right," we are transported back to the giddy feeling of falling in love.

Who should win this week's Pop Clash: Miley Cyrus or Taylor Swift? You can vote once per hour until the poll closes at 3PM ET on Sept. 23.
