Getting the current Media Player song

I've got a Forms application that needs to get the current song in WMP. So far, my code is:

Code:

---

Imports WMPLib

Public Class Form1

    Dim wmp As WindowsMediaPlayer = New WindowsMediaPlayer
    Dim playlist As IWMPPlaylist = wmp.mediaCollection.getAll()
    Dim media As IWMPMedia = playlist.Item(100)
 
    Private Sub next1_Click() Handles next1.Click

        Label1.Text = media.getItemInfo("Title")

    End Sub

End Class

---

As expected, this gets the Title of my 100th song and it does work. However, if I try Dim media As IWMPMedia = wmp.currentMedia and Label1.Text = media.getItemInfo("Title") I get a NullReferenceException

I'm pretty sure this should be possible as it's all there on the MSDN documentation, I just can't get it to work.
