You are right, AOR was still prevalent and quite a bit of decent, to great, music was recorded and released at the zenith of the disco era. But at that time, say 77'-80', disco music and all the ancillary BS related to it was so in your face at a time when the media was limited that it force fed America a popularity that was created for them.
I think disco's domination of pop culture during that era is one reason for yacht rock's resurgence today, as people discover, or rediscover, how good a lot of that music was.
"What a Fool Believes" was released by Kenny Loggins in the summer of '78 (and the more popular Doobies version in the fall of '78) -- the year five of the top 10 Billboard songs were by either the Bee Gees or Andy Gibb, along with one other disco song.
In '79, when the Doobies' release of "What a Fool Believes" hit No. 1, seven of the year's Billboard Top 10 were disco songs, with another one being a ballad by disco/R&B singers.
Heck, in '79, Leif Garrett's "I Was Made for Dancing" finished higher on the charts than Toto's "Hold the Line," Kenny Rogers' "The Gambler," Dire Straits' "Sultans of Swing," and other songs with far greater cultural staying power.
