Okay, here:
Code:
<embed src="yourfile.mid" height="45" width="300" autostart="true" loop="true">
Okay, you can only change the things I bolded. I think it's obvious what each bolded thing does. And, no, I did not put a music file in the code. You'll have to get your own.
If you have any questions, ask me. Also, when everything's ready, you can cut and paste this onto your UP.
And next time you should say please.
