"Respect", by Aretha Franklin, from USA, in 1967
Kate and Aretha battled it out for the #1 position. Aretha held it from a few days into voting, then Kate surged ahead to keep it for about 9 days in the middle. In the last 3 days though, Aretha came back and held her ground. With 7% more votes than "Wuthering Heights", "Respect" - a song written about how men deserved more respect from women - came to win the poll for the best female-performed song of all time.
This version is from a while back, and is faster than the version from the Blues Brothers you (like myself) may be familiar with. I quite like this, as it's nice and boppy and keeps moving along.
