This is completely normal. In fact, all musical styles have a certain arrangement that they follow. If you take any Music Appreciation classes or Music Theory classes in college they teach you exactly what the format of each style of music should have. It’s basically a rule of what makes each style of music (not that it has to be followed, but just a guideline). They use formats with letters with A being an intro, B being a verse, C being a chorus D being an outro etc. Then when you are asked to breakdown arrangement by listening to various tracks for a test you would write something like: A, B, C, B, C, D for a basic rock song.
I really enjoyed this class as they went through everything from Baroque to modern music. The funniest part was when the professor did role call and called my name (which is Bach) and said, “Bach???, you better get an A in this class!” To which I replied, “No, I thought I already inherited that.”
