New array for music symbols - actionscript-3

Question

I have background musics from the library, any ideas how to solve this code by clicking the button to change it?
var BeachBall: CrashBash_BeachBall = new CrashBash_BeachBall();
var BrickDive: LEGOIsland2_BrickDive = new LEGOIsland2_BrickDive();
var BloocheepOcean: MarioHoops_BloocheepOcean = new MarioHoops_BloocheepOcean();
var Underwater: MarioTeachesTyping2_Underwater = new MarioTeachesTyping2_Underwater();
var UnderPressure: CrashBandicootNST_UnderPressure = new CrashBandicootNST_UnderPressure();
var CalmWaters: DireDireDocks_CalmWaters = new DireDireDocks_CalmWaters();
var Level1: TreasureCove_Level1 = new TreasureCove_Level1();
var Level2: TreasureCove_Level2 = new TreasureCove_Level2();
var Level3: TreasureCove_Level3 = new TreasureCove_Level3();
var music: Array = new Array(CalmWaters, BloocheepOcean, UnderPressure, Underwater, BeachBall, BrickDive, Level1, Level2, Level3);
// Changing the Background Music
music_btn.addEventListener(MouseEvent.CLICK, on_pressMusic);
music[Math.floor(Math.random()*music.length)].play();
if(!sound)
{
sound_channel = CalmWaters.play(0, int.MAX_VALUE);
sound_channel.soundTransform = new SoundTransform(0.4);
}
function on_pressMusic(event: MouseEvent): void
{
/*
var random: int = int(Math.random() * sounds[0].length);
play_music(sounds[0][random]);
var sMusic:Button = new Button();
sMusic.play();
*/
if (is_Playing == true) //# if music is already playing
{
music_player.stop();
}
musicNum = Math.floor(Math.random() * (musicList.length-1));
music_object = new (musicList[musicNum]);
audioTime = 0; //# seconds to start from within track
music_player = music_object.play(audioTime);
is_Playing = true;
}
Error:
TypeError: Error #1007: Instantiation attempted on a non-constructor.

All of the codes are updated. any ideas how to solve and fix this for their future coding.

Answer 1

Try something like this:
var BeachBall: CrashBash_BeachBall = new CrashBash_BeachBall();
var BrickDive: LEGOIsland2_BrickDive = new LEGOIsland2_BrickDive();
var BloocheepOcean: MarioHoops_BloocheepOcean = new MarioHoops_BloocheepOcean();
var CalmWaters: DireDireDocks_CalmWaters = new DireDireDocks_CalmWaters();
var Level1: TreasureCove_Level1 = new TreasureCove_Level1();
var Level2: TreasureCove_Level2 = new TreasureCove_Level2();
var Level3: TreasureCove_Level3 = new TreasureCove_Level3();
var Underwater: MarioTeachesTyping2_Underwater = new MarioTeachesTyping2_Underwater();
var UnderPressure: CrashBandicootNST_UnderPressure = new CrashBandicootNST_UnderPressure();
var myNum :uint = 0;
var audioTime :uint = 0;
var music_object :Sound;
var music_player :SoundChannel = new SoundChannel();
var is_Playing :Boolean = false;
var music_list :Array = new Array();
music_list = [ BeachBall, BrickDive, BloocheepOcean, CalmWaters,
Level1, Level2, Level3, Underwater, UnderPressure
];
//# Changing the Background Music
music_btn.addEventListener(MouseEvent.CLICK, on_pressMusic);
function on_pressMusic (event:MouseEvent) : void
{
if ( is_Playing == true ) //# if music is already playing
{ music_player.stop(); }
myNum = Math.floor( Math.random() * (music_list.length-1) );
music_object = new ( music_list[ myNum ] );
audioTime = 0; //# seconds to start from within track
music_player = music_object.play( audioTime );
is_Playing = true;
}
