I think I know which song you mean lol! I also downloaded one, but it was called Sahira Bellydance music on Kazaa and Limewire.. I have had it for three years but I still haven't been able to find it's title.
I do know of some sites to host files. I'll look for those and post them here so you can put up the song. I'd love to know also what song it is.
You can sign up for free and get 500 mb free storage to share files. You upload the file (which may take a few minutes), then you click it and you'll get a link from where to download it. Paste the link here and we'll be able to download your song.
