Perhaps you want:

class foo init_song =
  let name, chan = open_temp_file ~mode:[Open_binary] "foo" "bar" in
  let () =
    output_string chan init_song;
    close_out chan in
  let the_song = load_music name in
object
  val mutable song = the_song
end;;

or even:

let foo init_song =
  let chan = open_out "foo" in
  let () =
    output_string chan init_song;
    close_out chan in
  let the_song = load_music name in
object
  val mutable song = the_song
end;;

But I'm not sure...
