Album rock listeners had it pretty good that year, with Pink Floyd's "The Wall", Tom Petty and the Heartbreakers' "Damn The Torpedoes", Bob Seger's "Against The Wind", Pat Benatar's "In The Heat of The Night", Blondie's "Eat To The Beat", Led Zeppelin's "In Through The Out Door", Styx's "Cornerstone", the Pretenders' debut album, Fleetwood Mac's "Tusk", Supertramp's "Breakfast in America", Molly Hatchet's "Flirting With Disaster", J. Geils' "Love Stinks", The B-52's debut LP, Foreigner's "Head Games", The Cars' "Candy-O", Journey's "Departure", The Rolling Stones' "Emotional Rescue" and ZZ Top's "Deguello" all making the list of the 40 best-selling albums of the year.
I'm glad that someone finally said that! I remember the rock being out there back in 1980. It was out there, but you had to dig a little to find it, especially if you were limited to top 40 radio. And nearly all the albums that you mentioned here charted at least a single or two, although some of these albums were indeed carryovers from 1979.
I think Fleetwood Mac got kind of a raw deal here, especially in this thread, because "Think About Me" was the only song by them mentioned on this list, and it only reached #20, as you said. But it
was the third single from an album which saw its first two singles reach the top 10. "Sara," the immediate predecessor to "Think About Me" as the second single from
Tusk, reached #7 in the winter of 1980, and would have been a better candidate for this list, because it was a Stevie Nicks song, and her songs tended to be their biggest and most enduring hits. (Her song "Dreams" was their only #1.) At the same time, though, the Mac really didn't help their own cause, because
Tusk was two years in the making, it was a double album, and that leadoff single (the title song) was a bit of a head-scratcher. All this coming on the heels of an album that had been one of the biggest sellers of all time, up to its time.
