I must be one of the few users on earth that does not have a Facebook account yet and who does not have any plans of creating one in the near future. Still, Facebook is extremely popular and this following Facebook application could be useful - I think it definitely will find lots of users who like it - for some users of Facebook.
FireTunes is a small application that changes the Send Message dialog box in Facebook. It extends the Facebook Send Message menu so that songs can be simply dragged and dropped in it as well. This works even out of applications like iTunes which is a very nice feature. If you do not want to drag and drop you can simply use the browse computer menu to locate and add music that you want to send to your Facebook friend.
The friends will receive the message that will contain a link pointing to the mp3 file(s). A click on the link will download the music to the users computer.

FireTunes is a extension for Firefox, so everyone not using Firefox has unfortunately no possibility to send music to his friends in Facebook unless someone else would create a similar add-on for Opera and Internet Explorer.
