Query: Good but tiring

The CD is good and very powerful. The reason I gave it four stars instead of five is that all the songs sounded the same. For the most part, it was literally impossible to tell where one song ended and another began. Usually I appreciate CDs more when some songs are fast, some slow, different instruments are used, etc. Still, the CD and messages are good and clear, and I would recommend the CD.
