Sia's Chandelier is back in the top 40, climbing from 83 to 35, probably thanks to former Liberty X singer Kevin Simm's rendition on last week's episode of BBC talent show The Voice.
Meanwhile Sia's album, This Is Acting, debuted at number three - behind Bowie, who held onto the number one and two spots.
Adele's 25 and Justin Bieber's Purpose complete the top five in the official UK album charts.
