I think, and I believe tee will agree, there's nothing wrong with posting it in the 80s thread as well as this one. In 1987 it was only released in their native country, Sweden, where it was a hit. The lyrics were slightly changed and it was released internationally in 1990 and became a worldwide hit (besides being in the movie soundtrack).
About a week ago I posted "Candle In The Wind" by Elton John. It was released - and was a hit at least somewhere in the world - in 1974, 1987, and 1997 so it works for all 3 decades in my opinion.
I think if a song is recorded and/or released and/or is a hit in a decade it fits that decade and it doesn't matter if it's the same artist or a different one. I would say - and I think this has been done - posting an 80s or 90s live performance of a 60s or 70s hit isn't fair unless it was a (top 100) hit once again.
Of course, this is just my opinion, other people may think differently and I can live with that - it's not like this is something super serious.
