This is interesting. At my library, all CDs are kept in the same area. Pop and Country CDs are most likely to go out and never come back. (Rap CDs are filed under "Pop", as we own too few Rap CDs to designate a new section.)
Some people have even snuck the CDs into the restrooms, broken the security cases and removed the discs.
Because the CDs are constantly being ripped off or damaged, the library purchases very few Pop or Country selections these days, and has basically nothing recorded within the last five years. Even so, albums by very popular artists, like Elvis and the Beatles, continue to disappear.
Frankly, I wonder why the library does not choose to place all Pop and Country CDs in a closed-stack area or just do away with the music-CD section altogether.
slops, gloops, and gruels.
