In case of Audatious running on X11 all you need is Python X library
http://python-xlib.sourceforge.net/

And something like:

from Xlib import display

dpy = display.Display()
root = dpy.screen().root

NET_WM_NAME = dpy.intern_atom('_NET_WM_NAME')
UTF8_STRING = dpy.intern_atom('UTF8_STRING')

for win in root.query_tree().children:
    try:
        window_title = win.get_full_property(NET_WM_NAME, 
UTF8_STRING).value
    except AttributeError:
        continue
    if window_title.endswith('Audacious'):
        song = window_title.split(' - ')[:-1]
        if song:
            print song
