From the little information you provided, I am taking a stab at this:
http://jsfiddle.net/V44fQ/
var app = angular.module('songApp',[]);
app.controller('SongCtrl',function($scope) {
$scope.edit_song = {};
$scope.song = [
{name:'Heartbreaker',artist:'Led Zeppelin',genre:'Rock',price:'.99'},
{name:'War Pigs',artist:'Black Sabbath',genre:'Rock',price:'.99'}
];
$scope.applySong = function(song) {
$scope.edit_song = angular.copy(song);
$scope.edit_song.song_index = $scope.song.indexOf(song);
};
$scope.saveSong = function() {
var idx = $scope.edit_song.song_index;
$scope.song[idx] = $scope.edit_song;
$scope.cancelSong();
};
$scope.cancelSong = function() {
$scope.edit_song = {};
};
});
