in Taurus that definitely evoke my recollection of Stairway, but not too much of the Taurus song is similar.

plagiarizing himself.

Almost all music, with the exception of highly experimental music, includes words, riffs, chord progressions, and other elements the have occurred before. That's what music actually is. It is a shared vocabulary of diverse musical elements. My favorite example is how West and Central African music came to America with enslaved Africans, morphed into gospel and blues after encountering European church and folk music. Then morphed again into ragtime and jazz. Perhaps an even more interesting example is how enslaved people in the Caribbean, and Latin America created Afro-Latin music such as the Rhumba when they encountered European music, which then moved back to Africa to become a whole popular genre of its own in the form of Congolese Rhumba.

And, we're talking popular form, so there isn't much call for odd time signatures or radical chord changes.
So, if you listen to any 1,000 songs we'd probably hear 50 things extremely similar, here & there. If not way more.
Watch a Later with Jools Holland earlier today. Sting played a tune and there were some areas where I could hear Message In A Bottle. Not identical, but pretty clear. I doubt that was intentional.
You're dead on. This case was nonsense and so was the Harrison thing.

If there is a BIGGER Led Zepp fan than me...I have not met that Person.

This little girl is only 8 years old.. Amazing!, just amazing. When I saw this I was shocked...
