You can probably guess what it does, but I'll tell you anyways. It has optional key-binding for Start CD, Stop CD, Next Track, Previous Track, Volume Up, Volume Down and Play whole CD. All info is showed in a HUD. I love this one myself.
Coming with the HUD shown above and NewOpts support for the keybindings.
The Scripts can't check the track amount on the CD, so just don't force it to play em.
Nothing crashing Tribes, but just ugly. Well, just don't try :)
