Actually, you only need to change the track URI and add an User-Agent
Use this function for the GetOAuth()
To translate it into C# use 
http://www.developerfusion.com/tools/convert/vb-to-csharp/

VB.NET:
    Public Function GetOAuth() As String
        Dim client As New WebClient
        client.Headers.Add("User-Agent: SpotifyAPI")

        Dim raw As String = client.DownloadString("https://embed.spotify.com/openplay/?uri=spotify:track:6uQ192yNyZ4W8yoaL0Sb9p")
        raw = raw.Replace(" ", "")
        Dim lines As String() = raw.Split(New String() {vbLf}, StringSplitOptions.None)
        For Each line As String In lines
            If line.StartsWith("tokenData") Then
                Dim l As String() = line.Split(New String() {"'"}, StringSplitOptions.None)
                Return l(1)
            End If
        Next

        Throw New Exception("Could not find OAuth token")
    End Function

I would suggest to use https://open.spotify.com/token instead of this 
embed.spotify.com hack.
