both
Code:
<embed src="the_name_of_ur_song.wma"  autostart="true" loop="true" hidden></embed>
and
Code:
<bgsound src=music/music.wma loop=-1 autostart=true>
are correct!

<embed> is support by Firefox and Netscape and require the size and show up
<bgsound> is support only in IE and always "hidden"

Thank you 'lost-strange' and "CFE_aAa_FeLoNy" (my man)... :D
