The supplied article consists only of a headline posing the question of which was the first electro pop song to reach the charts in 1972, together with website navigation links and a mailing-list sign-up prompt. No actual body text, argument or answer has been provided, so the substance of the piece cannot be summarised.

Because the article content is missing, it is not possible to identify the song the headline refers to, name any artist, or convey the reasoning or historical context the writer intended. Anyone seeking the answer would need to consult the full article at the source, as the material given here contains no reportable details, dates or figures beyond the year mentioned in the title.
