Swedish House Mafia’s Paradise Again (Island) could reach its highest position in the U.K. yet , #16, thanks to its release on CD. Vieux Farka Touré and Khruanbin’s Ali (Dead Oceans) is #19.

At singles, Sam Smith and Kim Petras’ “Unholy” (EMI) is set to be this week’s highest new entry—it’s currently #2, but has launched a challenge for the top slot occupied by David Guetta and Bebe Rexha’s “I’m Good (Blue)” (Parlophone).
