Absolutely agree with you. With many composers having an understanding of where they were coming from when they composed their music can make a huge difference.
In my experience most full price CD's do have a booklet with a thumbnail of the composer and the piece. Budget CD's can be a problem. For the more inquisitive, there are many books available for the most popular composers as well which are worth you time if you find youself interested in their music. There are other books available which will give a good overview of the history of classical music from the early ages thru to modern compositions. I believe that understanding the whys of the importance of composers/compositions to their times can also enhance your appreciation of their music.
