I am looking at my CD storage unit now. It reads as follows.

Folk
Folk Compilations
Blues
Jazz
Classical
Classical Compilations
Pop & Rock
Sinatra
Humour


I used to have a section of Mudcatters CD's, but I have now melded them into the general meleé

My cassettes are mostly either Classical or Folk, and are in alphabetical oreder. I am gradually transferring them to CD's

I have some audio books on cassette too.
