public const int KEYEVENTF_EXTENDEDKEY = 1;
public const int KEYEVENTF_KEYUP = 2;
public const int VK_MEDIA_NEXT_TRACK = 0xB0;
public const int VK_MEDIA_PLAY_PAUSE = 0xB3;
public const int VK_MEDIA_PREV_TRACK = 0xB1;

[DllImport("user32.dll", SetLastError = true)]
public static extern void keybd_event(byte virtualKey, byte scanCode, uint flags, IntPtr extraInfo);

keybd_event(VK_MEDIA_PREV_TRACK, 0, KEYEVENTF_EXTENDEDKEY, IntPtr.Zero);
