Pete,

Thanks a lot for the information. As usual you provide fast and accurate

I really don't need to get too much info about the song, mainly static
info that I can get with ID3 (I've used it heavily in the past to fix
id3-tags for my mp3-collection).

I have a proof-of-concept thing up and running now. I loads playlists and
sets a random background image, plays mp3:s as well as has some basic
interaction with the user.

Howver, smpeg:s mp3 support is quite bad. Far too many of my mp3:s don't
play with it. Sure, they probably don't follow standards etc, but xmms
plays them just fine. So I'm wondering wether this will work out in the
end.

This does not work for me. I never get any event of this type. I have to
manually use my "next" funtionality to proceed to the next song. The code
I use looks like this:

def play ():
    global currentSong
    
    # get a random song
    index = whrandom.whrandom ().randint ( 0, len (playlist) - 1 )

    # store the name of the song
    currentSong = playlist[index]

    # load the song
    pygame.mixer.music.load ( currentSong )
        
    # make sure we know when the playing has stopped
    pygame.mixer.music.set_endevent (USEREVENT) 

    # and play it
    pygame.mixer.music.play ()

Sure, it runs windowed too, but I'm not sure wether I'll give it any more
time, as too many songs don't work.
