An update to this post.....I sent the SGB discs back and the Ebay vendor replaced them. The new discs have problems also but not necessarily on the same tracks. During the download, the indicator will lock up on these tracks and you must cntrl-alt-del to close. Does the same thing when you click disc under "find singer's song." I assume that during a show when you were trying to download a singer's track, if this same thing happened, your program would crash.
