47.
Faith - George Michael
This came out in October of 87 and began climbing the charts to become the number-one single the next year in 1988. The eponymous track of the album Faith that became one of the best-selling albums of all time having sold over 25 million copies worldwide and was certified Diamond by the Recording Industry Association of America in 1996.
A few years before this came out, when Michael was still with Wham my gf had a crush on Michael making me hate him and I pretty much hated everything he did up to this song but still resisted until a guy from work went nuts over this song and would blare it whenever it came on the radio, and in 1988 it was played a lot.
I remember when I decided that the song was pretty good, lol.
