THANKS TO THE PARENTS’ Music Resource Center (PMRC) for explaining the lyrics of Pearl Jam’s “Immortality” (“Dirty War,” 8/25). One of my favorite and perhaps the most cryptic of Pearl Jam’s songs, “Immortality” defied all my interpretive skills as an English major and editor, but now I know it is a profane and subversive call for “suicide as a solution to life’s problems.”

Amazing that something so difficult to understand could be so dangerous! Does the PMRC read palms, too?
