Faithless Love
did make the Top 10 Country songs via Glen Campbell's 1984 rendition.
Unfortunately there were no country songs in the
overall Top 10 of 1974.
Unless you count Olivia-Newton John and John Denver as country (kinda-sorta) the highest-ranking Top 40 song in 1974 that was a country tune was Charlie Rich's "The Most Beautiful Girl" - which I would still gladly pair up against Florida Georgia Line above.
At any rate I'd be glad to hear a recent country tune - well-known or not - which can even remotely compete with Faithless Love.
