Renaming entries in the user's library

My Question or Issue 

When one adds an album to the local library, that entry may be listed under the name of the album, the given name/surname of the composer, the given name/surname of the performer, etc.

Thus, even though the library entries are listed in an alphabetical order, it is difficult to locate a particular entry in a large library.

 E.g., some works of Johann Sebastian Bach in my library are listed under B (Bach), some under J (Johann), some under F (Fugue), etc.

 How can one RENAME the entries so that the library is organised in some logical order?

Using the above example, I want to rename the entries so that all the works of J.S. Bach are listed under B.
