12 songs from one Taylor Swift album in the top 40? That never happened in the 60’s to 80’s.
I would have thought The Beatles might have pulled something like that off.
20 #1 hits is pretty good, enough for a CD.
IIRC, one week the Beatles had Top-40 spots #1, #2, #3, #4, #5...on 3 different record labels no less!
