duplicatemovieclip / buttons

i want create duplicate buttons and add actions to each of these new buttons...

the below doesn't work..all the buttons just have the actions for the last button...any suggestions?

for (i=0; i<mp3number; i++) {

// duplicate movie clip and make visible
_root.mp3item.duplicateMovieClip("mp3item"+i, i);
_root["mp3item"+i]._visible = true;

// add relevent text to textfield within movie
_root["mp3item"+i].mp3info = _root["mp3text"+i];

// move movie clip further down
get_y = get_y+20;
_root["mp3item"+i]._y = get_y;
}

//
// set mp3 download and play buttons
//
for (i=0; i<mp3number; i++) {
geturlinfo = getmp3links[i];
_root["mp3item"+i].mp3download.onRelease = function() {
getURL(geturlinfo, "_blank");
};
_root["mp3item"+i].mp3play.onRelease = function() {
setmp3 = i;
gotoAndStop("playmp3");
};
}
