This is a cover of a song by The Kinks. When original writer Ray Davies was interviewed by MassLive in 2009, he said:
I […] liked the Van Halen version of ‘You Really Got Me,’ because it made me laugh. It was like playing with Metallica. It was all done with good spirit and good humor, it made me smile. That’s the key thing.
His brother Dave Davies, on the other hand, showed contempt in a separate 2010 Pulse of Radio report:
There’s the thing: good art isn’t always about having the comfiest technique. I shouldn’t encourage him, but I’m sure Eddie Van Halen played better when he was drunk. But it must be a good record if people like it. [Their] version was very Middle America. It was like, ‘Hey man, look at me with my tight trousers! Here’s our version of 'You Really Got Me’!
It predates Van Halen’s 1978 eponymous debut album by a month, being released as a single alongside “Atomic Punk” in January of that year.
