Disklavier

Hi,

I am a newbie to the Disklavier. I just bought a GH1 Mark III (year 
2000). 
Question 1: I downloaded midi songs into the floppy disk and load into 
the mark 3. All songs come up without titles. The display 
shows "Untittle". How do I name the songs? IS there somekind of 
software to name the songs?

Question 2: All songs seemed to play in alphabetical order. How do I re-
arrange songs in my own ordering?

This is a great site. I am a newbie so any help is greatly appreciative.
