The most trivial example of what?
Nothing about Penny Lane changed. It’s the same exact song - the same exact set of sounds. Our society decided that the rules about who can and cannot play those sounds (for commercial purposes) have changed, but nothing about the song itself has changed, so I’m unsure why you would expect to find a difference with the song itself.
They’re all different renditions of Penny Lane.
Are you familiar with a concept called context? In the post I was responding to, they were talking about Penny Lane.mp3. Obviously, an mp3 file is going to contain a recording of just one rendition of the song; there may very well be other commercially available renditions of the song.
If I say that “this is a table”, are you going to sputter about how many other tables exist in the world, so how could I possibly say that?
Sometimes, a word can mean multiple things! Gasp!
Yes, you can use the term “Penny Lane” to refer to the lyrics, as in the case where you sing Penny Lane at the pub. Or you could use the term to refer to the Guitar Hero level (just kidding, Penny Lane isn’t featured in Guitar Hero!). What a profound observation!
Correct, there are lots of other things you could also call Penny Lane. I was responding to a guy talking about a file named PennyLane.mp3, so that’s the context I was speaking in. In other contexts, other things are also Penny Lane, including a physical street in Liverpool.
If we were totally ignorant of all of that history because all references to the Beatles were wiped out in the Great War of 2076, and all we had was a scratchy record with Penny Lane on it, we could still identify it as art.
