background sound in Html with differint browser???

[gamesmell]

I know for IE its <bgsound src="your music here">

but its differint for the outher browsers
so what is it for the outher browsers like netscape or Mozilla and the outhers


Edit: maybe I could add it in flash somehow so I would not have to worry about browers compatabilty info on that would also be helpfull also (I already have flash MX 2004)
