I have some problems with this player:

After pressing play the pause button doesnt show up, ive tried setting
it to “true” but this happens;

Here is the action script, i have highlighted the play/pause functions (line 4/5)

//playing first track
//playTrack(tracks_array[0].source,tracks_array[0].artist,tracks_array[0].album,tracks_array[0].title,true);
play_btn._visible = true;
pause_btn._visible = false;

//loading first cover
cover_loader(0);
//populating list with song titles
populateList();
}

//play track function
function playTrack(source, artist, album, title, stream):Void {
artist_txt.text = artist;
album_txt.text = album;
title_txt.text = title;
soundPlayer = new Sound();
soundPlayer.onSoundComplete = function():Void {
//lets play the next song
if (selectedTrack<(totalTracks-1)) {
selectedTrack += 1;
} else {
selectedTrack = 0;
}
playTrack(tracks_array[selectedTrack].source,tracks_array[selectedTrack].artist,tracks_array[selectedTrack].album,tracks_array[selectedTrack].title,true);
cover_loader(selectedTrack);
updatevolume();
};
soundPlayer.loadSound(source,stream);

clearInterval(songInterval);
songInterval = setInterval(songProgress, 100);
}
