and/or musical data, executing this command will erase the
data of that song and rewrite it with the data from the copy
source. Before you execute, be sure that you will not be
losing important data.
5. If you check Replace to original Song in Cue List and
execute this command, the Current Step song will be

If you execute without checking this box, the newly created
song can be selected later for the desired step of the cue list.
