My biggest area of expertise is music -- especially pop, country and Christmas music. I've written, and had published, more than two dozen music-related books. I will make a conscious effort not to quote my own books. So far, so good. :)
I have a large music collection, with over 15,000 45s and thousands of LPs and CDs also. You'll start to see fewer "Cover Not Available" images for singles in the coming months.
I also have a keen interest in, and knowledge of, sports. I have many other interests as well; you never know in what article I might make a tweak here and a fix there.
