What is this? SImple Save - Music and iTune Backup thingy...  

I keep downloading tunes to CD. I want to copy my DVD family movies from the disks of the camera to a regular size disk and pass to the family members. Plus I wanted to download songs and burn to disks.

I saw this in the store and bought it, but better ask what I am buying incase I don't understand it.

It says on the box

Music & iTune Backup / SImple Save / I can Save Your Memories
Music and iTune b ack up Disk
Automatically finds, organizes and backs up your music files. No software to install. Record-Once DVD. Store up to 5,000 music files per disc.


Now.. anyone heard of such a thing? It is made by Memorex. It says Record-Once - does that mean I have to have all songs I want to copy to it available as I can only copy songs to it once... meaning I can't do 20 or so now and add any more later? I guess if you have tons of songs but for just a regular kind of person... who has 5,000 songs on their PC?

Anyone have any comments, thoughts or suggestions?
