the reason you will not see a license on the disc that are out of print is most likely because the writer on the artist or the rec company most likely sued
them to get the disc off the shelf
there are a lot of cdg company dont pay for the rights to print the songs they are using at least not all of them
so when you see a disc out of print that is most likely what happin

dont know what to tell you here
in a case like that its up to you to do what you have to to protec your disc
