Even though the Internet in 1980 was more idea than reality, there was a lot going on in 1980 in music.  Pop and rock still needed the spirit of radio to keep them alive (what a Rush!).  Sounds started to change, and the US and the UK grew closer musically, whether it was from the untimely death of John Lennon or the New Wave of British Heavy Metal (MWOBHM) waiting in the wings, 1980 was a pivotal year for music.
