A federal jury sided with Led Zeppelin on Thursday in a lawsuit that alleged the band stole its opening riff to 1971 classic “Stairway to Heaven” from a song by the band Spirit. After a six-day trial in Los Angeles, jurors ultimately decided that while there was a reasonable chance guitarist Jimmy Page and singer Robert Plant had heard Spirit’s “Taurus” before writing their own song, and could have conceivably lifted the riff, the two songs were not “substantially similar” enough to suggest copyright infringement.
