Here I go on my 2nd request to identify artist and song - you did so well with my first request. I think this one will be easier.
It was a song played in the discos in the 70s and 80s. Pretty popular. I'm thinking it could be considered dance/pop too.
Female artist
Pretty sure she was black
First artist I think of is Donna Summers, but checking iTunes none of her songs sound like what I'm looking for ... would help if I heard the beginning of the her songs on iTunes.
It starts out with the artist going/saying something like ooooouuuuuuuuu for an extended time peroid, like you without the y and it's kind of erie/haunting. Then it turns into quite a fast pace beat song.
Sorry, this is all I can give you. TIA - Jim
