OK, before the year 2000, and what memories it brings back.
Can't say this is the only "favourite" song I have, there must be several, for varying reasons.
I (male) remember always having had some doubts about my sexual preferences, and then I heard this Spanish song "Mujer contra mujer".
I was switching channels on my TV set, and then came upon the only Spanish TV station on cable we have here : TVE (internacional).
There was a huge crowd, and I think most of them were girls, they had their lighters on, and moving along to a very intimate song.
I understood that this was about the love between two women.
At that time I did not understand Spanish yet, and I guess it was one of the reasons for years later to study that language.
The lyrics are quite nice.
Here's the beginning:
"Nada tienen de especial
Dos mujeres que se dan la mano
El matiz viene después
Cuando lo hacen por debajo del mantel
Luego, a solas, sin nada que perder
Tras las manos el resto de la piel."
There is nothing special about it,
Two women holding hands
The nuance comes afterwards
When they do this underneath the table cloth
Later on, when they're alone, with nothing left to lose
After the hands comes the rest of the skin."
