This is why I get so angry at all the self-righteous "PEOPLE PLAGIARIZED MUSIC AND THEY WEREN'T TALENTED AFTER ALL!" BS millennials and younger post on YouTube. Before the mid-70s or so, everyone borrowed everyone else's music and they were cool with it.
When bands started filling arenas and records started going double platinum, it attracted lawyers who started suing to get a piece of the pie. The Beatles, Rolling Stones, Led Zeppelin, The Who, The Doors, Bob Dylan....all of the 60's and 70's bands used other people's music and reinvented it. Before lawyers, musicians were flattered if they came up with something other people latched on to.
