How can I send a MP3 as an attachment?

With Outlook 2003 how can I send a MP3 as an attachment, like I would a doc or a pic? Any ideas?

 

@Kes - This is for Outlook Express, not Outlook 2003.

@MTHall51 - not sure you can with Outlook, due to inbuilt limiting. Instead you could upload the file to yours or someone else's website, or a blogsite and then send friends a link directly to it.

 

I've done it in gmail. I can't remember, but you might have to change the file extension. You could always compress it in a .rar or .zip file. Almost all PCs have both.

 

That was my suggestion too This is how I send several photos at the same time using both GMail and Yahoo mail. I put several photos into a folder and zip it, then send the zipped folder as an attachment. You can do the same with music files. But, I'm not an Outlook (or Outlook Express) user so I have no idea if this will work, theoretically, it will.
