Answer 1

To make play behaviour eexplici on a button click , refer this:
Xaml :
<MediaElement x:Name="media" Source="{Binding
ElementName=listbox,Path=SelectedItem}"
LoadedBehavior="Manual" UnloadedBehavior="Manual"/>
<Button Click="Button_Click" Height="27" VerticalAlignment="Bottom"
HorizontalAlignment="Left" Width="62">Play</Button>
Code Behind :-
private void Button_Click (object sender, RoutedEventArgs e) {
media.Play ();
}

You should implement business logic to browse the directory you are targetting. Prepare a collection of Items. Bind these to Listbox
For playing the song, bind selected item to MediaElement.
I will try to compile some simple solution and update if you still need further help.
Updating simple solution:
Xaml:
<StackPanel Orientation="Vertical">
<ListBox ItemsSource="{Binding}" x:Name="fileList"></ListBox>
<MediaElement x:Name="mediaElement" Source="{Binding ElementName=fileList, Path=SelectedItem}"/>
</StackPanel>
Code Behind:
public partial class Window1 : Window {
ObservableCollection<string> mFileList;
public Window1 () {
InitializeComponent ();
GetFiles(#"..\songs");
this.DataContext = mFileList;
}
private void GetFiles (string folderPath) {
string[] files = Directory.GetFiles(folderPath);
mFileList = new ObservableCollection<string> (files);
}
}

You need to handle the mediaended event as below :-
<MediaElement x:Name="media" Source="{Binding ElementName=listbox,Path=SelectedItem}" MediaEnded="media_MediaEnded"
></MediaElement>
Codebehind :-
` private void media_MediaEnded (object sender, RoutedEventArgs e) {
if (listbox.SelectedIndex < listbox.Items.Count - 1) {
listbox.SelectedIndex = listbox.SelectedIndex + 1;
}`

You need to handle the mediaended event as below :-
<MediaElement x:Name="media" Source="{Binding ElementName=listbox,Path=SelectedItem}" Margin="0,119,78,64" MediaEnded="media_MediaEnded"
></MediaElement>
private void media_MediaEnded (object sender, RoutedEventArgs e) {
if (listbox.SelectedIndex < listbox.Items.Count - 1) {
listbox.SelectedIndex = listbox.SelectedIndex + 1;
}
}
