The Beatles' loss of Northern Songs was a major setback for the band. It meant that they would no longer receive any royalties from their songs, which were some of the most popular and successful songs of all time. It also meant that they would have no control over how their songs were used, which could have led to them being used in ways that they did not approve of.
The loss of Northern Songs was a major disappointment for The Beatles, but it also served as a wake-up call. It made them realize that they needed to take control of their own business affairs and not rely on others to do it for them. As a result, they formed their own record label, Apple Records, and they began to take a more active role in their own management.
