The CDs appear to have some kind of copy protection which prevents them from playing properly in all CD players. For example, they do not play correctly on my computer but they do play in my home stereo system. I have read that copy protection systems will prevent a CD from playing in computers as well as some types of car stereos and portables. I did not check to find out if it will play in my car stereo and my portable CD player.This is not acceptable to me because I often use my computer for casual listening. I also make a "car copy" of any CD that I use in my car stereo and this CD cannot be copied with my computer.Although the music is every bit as good as the others reviewers have said, I have returned this recording, and one other new London recording which had the same problems, because I do not want to be restricted in the equipment that I use for listening.
