The song is Swift's seventh total AC No. 1 and first since "Style," from her prior LP, 1989, in July 2015.   Swift's seven AC leaders are the most among all acts since she first reigned with "Love Story" on June 6, 2009; Adele ranks second with five No. 1s in that span, followed by P!nk, with four.   Isn't it? Isn't it? Isn't it? Isn't it?       https://www.google.com.ph/amp/s/www.billboard.com/amp/articles/columns/chart-beat/8474633/taylor-swift-delicate-
