In 1998 I heard a song which started with a bit of rain or just loud droplets and I really want to find it. The lyrics were in English. It's possible the song is a bit older than 1998. It was a pop/dance song. And I am quite sure it wasn't any popular artist. I think it was a female voice and the song was "fast".
I've found the song. Not exactly "rain" at the begging.
