2 ) “Whole Lotta Love” (1969)
Led Zeppelin released relatively few singles. Instead, they encouraged fans to listen to entire albums. The band also frequently avoided television appearances, choosing to invite fans to attend their concerts instead. “Whole Lotta Love” was released as a single from the group’s second album and became the biggest hit song of their career. Peaking at #4, “Whole Lotta Love” is one of the hardest rock songs to be played widely on AM radio. Many radio stations edited the jazz-oriented middle section that features a theremin and moans from lead vocalist Robert Plant out of concerns for on-air decency. “Whole Lotta Love” was inducted into the Grammy Hall of Fame in 2007.
