Led Zeppelin "Stairway To Heaven" (1971)
Dolly Parton "We Used To" (1975)
Where They Sound The Same: The opening 10 seconds are almost exact matches.
In 2002, Dolly Parton covered "Stairway To Heaven," but long before that there was "We Used To." The song was released as a single in 1975, not long after Led Zep released the epic "Stairway." After hearing the first few seconds of Dolly's new single, it was impossible for critics not to notice the similarity.
