About the songs..
Try renaming the song from
"01 - Star of the Sea"
to
"01Star of the Sea"
or
"01-Star of the Sea"
or
"01_Star of the Sea"
In karaoke databases the "space dash space" ( - ) designates a "break" in the filename, so you can use a database program with them to sort them by 3 methods:
Example:
SC8146-12 - Charlie Daniels Band - Uneasy Rider
"SC8146-12" represents the disc# & track# (Sound Choice 8146, track 12)
"Charlie Daniels Band" represents the artist
"Uneasy Rider" represents the title
You can sort by disc, by artist, or by title.
