Inspiration or plagiarism?

In 2015 the Blurred Lines case inspired me to deal with musical plagiarism. Back then I browsed through some classic and new cases and developed my own methodology. In an essay I summerized my thoughts on plagiarism and inspiration.

Songs that were analysed in this paper, plus brief judgement by me:
Stairway To Heaven - no infringement,
Come As You Are - infringement,
Another One Bites The Dust - no infringement,
Blurred Lines - no infringement,
Sweet Child Of Mine - no infringement,
My Sweet Lord - infringement,
All About That Bass - no infringement,
Get Lucky - no infringement,
Viva La Vida - no infringement,
