This was Luxembourg's end of the year countdown of the biggest chart hits of 1973. I'm not all that sure what parameters they used to come up with the top 30. I notice that no artist appears twice, so I'm guessing it was the best song of the year per artist. All of the top 9 apart from Roberta Flack reached number 1, she only got to 6, so not sure why she would be placed second.
