I think this is partly true. However, there is a significant phenomenon where there is financial/political pressure to play songs (pay to play) which then creates demand for songs since they are then familiar to listeners. So companies/firms can pay stations to play otherwise unremarkable music (perhaps simple songs or those with the highest profit margins/potential available to stakeholders) and in a general sense this influences listeners to want to keep hearing those now familiar tunes. The whole pop-ephemerality of music-as-a-commodity feels like the new opiate of the masses - in general people are more content as long as they have a meaningless tune as the background soundtrack for their day-to-day repetitive tasks. I wonder what the correlation is between acceptance of repetitive music and the repetitiveness of a listener's daily tasks.
