I'm not sure about the rules of submitting something like this to Hacker News, but I found it to be a fascinating quirk at the intersection of culture and technology. I didn't even know about it (the radio edit) when I started researching this song for my website. The gist is below.

The Knack's 1979 breakout hit My Sharona is remembered for spending six weeks at the top of the Billboard Hot 100, but that radio edit is woefully incomplete. Lead guitarist Berton Averre’s full-length My Sharona solo is absolutely transcendent. Which makes it all the more ridiculous that it was cut for time on the radio release.
