Package to control command line CD players. See the code Lisp:cdi.el.
Just run the ‘cdi-start’ command, which will pop up a *cdi* buffer with the status of the CD (eg Playing) and track/artist information.
Various functions are bound to keys in the *cdi* buffer, eg ">" is bound to ‘cdi-next-track’ – use ? or C-h b to find all the bindings.
