Led Zeppelin Sued over ‘Stairway to Heaven’ Chord Progression

From a musicians stand point, someone who studied music in college, this whole thing is kind of silly. There are only a limited number of chords at your disposal. And those chords can only be placed together in a finite number of ways that make sense. Eventually, someone will write something that sounds similar to something else. Especially when you're dealing with similar genres. My personal opinion is that if it isn't blatant, let it fly.

That's not how the law works though. Even if unintentional, you can't profit using something that someone else created/discovered. I bring up the Coldplay/Satriani case again. I doubt Coldplay even knew who Satriani was let alone intentionally stole his music. Yet they paid him to settle rather than face what was surely a losing case. I think this case is even more explicit and the actual connections and relationships of the musicians are incriminating.
