      Although the No. 1 single “As It Was” set the shimmying, shimmering stage for the album — with its ’80s pogo pop that has you breaking out your best Molly Ringwald moves — the second half of “Harry’s House” settles into dreamy, woozy balladry that will have you booing up. Or getting on Tinder to find one.
