Query: An excellent self-expressive, mature effort

The last Tiffany album I bought was Hold an Old Friends Hand which I found to be as good as suger-coated pop can be. With the Colour of Silence Tiffany has improved on that album with self-expression, mature lyrics, and plain old-fashioned good music. The sad part is such an excellent album won't be heard by a majority of the people because of non-existent marketing and distribution. I only knew about this album because of VH1's Behind the Music. Isn't Tiffany the only artist on Eureka Records with several number ones to her credit? Maybe she deserves more of the machine working in her favor.
