The Kinks originally recorded "You Really Got Me" in 1964, but elected to cut it again; the second version is the one we've come to know and love. To explain why and how this song works would be against its very nature; it operates on a purely visceral level. Those chords, the riff, and the sentiment "you really got me" are basically all you need to understand its essence. At the time, it was likened to a play on the ambiguous "Louie Louie," another classic from the era. But a few facts are in order: Dave Davies' fuzz-tone guitar was a groundbreaking sound at the time, achieved by him cutting the speaker of his amp with a razor blade and poking pins into it. The song was a million-seller. The band adapted and adopted its riff and phrasing throughout their career -- from the immediate follow-up, "All Day and All of the Night," on into the '80s on songs like "Destroyer." Naturally it was a live concert staple. "You Really Got Me" remains a blueprint song in the hard rock and heavy metal arsenal. In 1978, Van Halen recorded a white-hot cover version for their debut album. With Eddie Van Halen's fret-board histrionics and David Lee Roth's vocal shenanigans, Van Halen made the song their own; it's a close second to the original and the airplay it has enjoyed on classic rock radio is rivaled only by the Kinks' own song. In 2000, as the song was approached the 40-year mark, The Gap clothing company used it in two television commercials for its children's line: one features a girl band doing a punked-up version, while the boys give it the hip-hop treatment. All that's to say that it's nearly impossible to mess up a truly extraordinary rock & roll song like "You Really Got Me."
