Maybe I was at the wrong track. What I like to acomplish is load all my songs from C:\Music (5600+) and play them randomly. If there is a song I like to transfer to a DISK, I use the command SongToDisk, then a screen pos up where I can select the disk I want to add the song to and it keeps playing my library. Next, I have a DiskChanger.skin where I can select the disk I want to load, all fine it does that. Now, I want to go back to the library and unload the disk and keep playing my library as befor. Is that possible?
