HOW-TO play .WAV file DURING THE TIME AN E-mail IS OPENED?

[TheFoglers]

I would like to have a music file (.WAV, MP3, etc etc) play DURING THE TIME,
the recipient has my e-mail open. The music is like a background while they
are reading the mail. It is mostly for effect, or too enhance my e-mails.

I recommend against it. It will most likely annoy your recipient, not
enhance your message. In the event you still want to do that, take a look
