I just found a list from the Swiss newspaper "Le temps".
https://www.letemps.ch/culture/jukebox-ideal-xxe-siecle
Here is their introduction:
"Is it possible to list the 100 best songs of the XXth century, that is to say published before the end of the year 2000? On paper, the undertaking looked a bit crazy, as it was necessarily subjective. Should it be based only on sales or online listening, or should we try to measure the importance of a song in terms of the traces it has left in the history of music? It is finally this second solution that Le Temps has chosen in order to propose a jukebox of the past century through the prism of a specialized jury, composed of journalists and collaborators of the newspaper, but also of professionals working in the music industry.
In the end, 25 people answered the call and proposed their list, sometimes common in the case of the programming teams of Montreux Jazz or Paleo. The idea was to select titles that were considered essential and to avoid too personal choices, in order to be able to draw trends by counting the votes received by the different titles."
