Is there a way of doing it?

Some say I have 'way too much time on my hands.

In OE when I mail my friends and family, I dress it up with stationary, 
various fonts and so on. I also insert a midi file which plays when the mail 
is opened. They all seem to enjoy it. Recently I decided to send an MP3 
which I inserted as 'background' from the Format toolbar the same as I was 
doing with MIDI. But apparently no one was hearing any music. When I went 
into 'Sent' and opened it, the music file played so I thought they also 
heard it.

It seems a WAV. or MP3 file can't be inserted except by attachment which is 
no big deal because anyone getting mail from me will not hesitate to open an 
attachment. I just wondered if there was a way to have a music file other 
than MIDI play upon opening the mail.
Now if someone else has more time on their hands than they should have would 
you let me know if I'm bangin' my head against a wall?
