Is there any other formats that can be played in your website?

Hello,
I have experimented a little and have music playing on my website,I was wondering though if I can play other formats like WMA because the sound file I have playing right now is a mid(MIDI)

also if there is a mp3 to MIDI converter please post the link,thanks:)

I've seen it done, but it isn't pretty for dial-up. ;)
