OK, so with a little help from Dr Wikipedia, here is my chronological selection of classic albums and standout tracks released in 1978. Including a few disco or disco-adjacent numbers that rinse the foul taste of the Bee Gees from the genre's mouth, in my opinion.
The taste for these was acquired later, as I was only 7 at the time, except for The Police, who I was precociously into, and Gerry Rafferty, who my Dad played a lot.
Gerry Rafferty - City to City - Baker Street
Kate Bush - The Kick Inside - The Man with the Child in His Eyes
Elvis Costello - This Year's Model - Pump It Up
Kraftwerk - The Man-Machine - The Model
Boney M - Nightflight to Venus - Rasputin
The Who - Who Are You - Who Are You
Tom Waits - Blue Valentine - Christmas Card from a Hooker in Minneapolis
Barry White - The Man - Just the Way You Are
