Meant to add that you can add your own categories in JRiver in order to organize your collection (called a Library here). So, I define each rip with the qualifiers "genre" and "period" and can then use the advanced menu creation ability to search on these items nested in any order.
So, if you are in a mood for romantic music, you go to that menu then choose from the subheadings for "Orchestral," "Choral," et al. The picture of the albums available then appears with all of the track info.
Works great for large collections and allows you to custom tailor your collection according to your particular listening habits. No matter how orderly my CDs are grouped, I still could not access them in this friendly a fashion.
