4. “TRXYE,” Troye Sivan: South African-born, Australian actor and YouTuber Sivan seems poised to be the next great male voice. (Watch your back, Sam Smith.) His “TRXYE” EP is gorgeous from start to finish, a swirl of dreamy pop that feels both nostalgic and bracingly current all at once. Sivan has a plainspoken way of singing that syncs perfectly with the gauzy production. And at just 19 years old, he’s only going to get better.
