website that allows mp3 distribution using unique codes distributed to people?

[MarcoSP]

is there a website that would allow me to create different codes to be sent to different people so they could download files (my music) from the website ONCE? I mean, a person gets a url with a code that allows him/her to download songs once, and then the url doesn't work anymore.

Any ideas? Thanks in advance!
Hi Andrew,

Thanks for your suggestion but I need to send a file directly to people's emails (or send them a link to the file), I don't want to have to explain to them how to download torrents (I love torrents, but not everybody know what they are). I'd have to tell them to install software, etc...
Besides, some of those people are in the US, so piratebay is out of the picture...

Thanks anyway, if you know a website like wetransfer that allows sending files to THOUSANDS of emails please tell me.

If I understand correctly, thepiratebay.org (or .se) allows this to occur. Beware: This site is illegal in the US and most other countries with copyright laws.

You will need an application called uTorrent
Got to uTorrent.com (first link in Sources) to get the client for free (this website is the official website and offers it for free. It is also the only website that I know that has a safe download of the client)
Install using advanced settings and deselect all all the addons that are irrelevant.
Complete the installation by following the on-screen prompts

Search for the song on the second site provided in the Sources
Click Get This Torrent
Download the torrent
Follow the steps provided in the description or comments section
