playing QuickTime files from a html link

as this is my 1st post i would like to say hi to....everyone....anyone!
ok here goes.......i've been stuck on this problem for a few days now.
i have a designed my own homepage with various links to diferent web sites, i also have a link to my own music page. on this page i have all my fav music which i want to click on, so my music plays in the background whilst i use my laptop. the problem is i want these links to play in/using quicktime. this seems to be ok when the link is a mp3 extension, but i also have m4a extensions in this collection which when clicked on opens up itunes. i really don't want to open this application. is there anyway in which to play these m4a's so that QT opens up isnstead of itunes. i want to keep itunes as my default player.
i would be VERY grateful for any help from you guys....even if it's to say it can't be done.
thanks for you time.

forget to say that the music files are in the same folder as all relative html/css files for this webpage.....and that the webpage is not online but only in my C drive.......thanks.
