How do toi think that The Beatles changed music?

Well for one thing, they incorporated eastern musique and instruments into western pop and rock music. (Ex: They used the sitar etc.) I also think they led the British invasion, which greatly influenced American pop and rock. They showed how creativity, even if it's weird, is great. Without their strange lyrics and sounds, we wouldn't have a lot of those 70's and 80's songs we love, like rock lobster. They encouraged difference in the musical industry.
