Postcard.fm - A Postcard with a Song

Postcard.fm is a nice little application that generating a postcard from the image+audio files that you're uploading to the site. All you need to do is to choose image & song (20MB max) from your computer, add a short message (if you like), and send it to your desirable recipient email address.

Link to this postcard.

Well, it seemed cool to send private music postcards to friends, but I reallly don't like services that don't write few words about themselves. And I certainly have no idea where all this music files are going... so use it at your own risk. 

No sign-up required.
