Feel free to disagree.
And I do. Strongly. I find what you're saying to be more than a little bit narrow minded. The Beatles for instance wrote tonnes of songs about love. Are you going to suggest that the meaning of each of their songs is exactly the same? I find that to be a ridiculous proposition.
It was relevant to this...or had you forgotten but if you want relevance to previous, let me see.
Medieval song is more in the realm of Black Sabbath and Zeppelin,
Black sabbath is not known for their love songs, I'm not too familiar with their material as I thought they sucked but I cannot think of a single love song unless it was about their love of drugs such as "sweat leaf" or "snowblind" although I suppose "Iron Man" could be about a guy with an erection, I kind of doubt it.
I am more familiar with Led Zeppelin and I'll say this: their first album does not appear to have a romantic love song being almost entirely misogynist in flavor. This trend seems to permeate their albums although after while they did move on to other themes. They were not known for love songs.
By the way, playing dumb is not a veryy friendly conversational tactic but lets leave that aside.
Your love song hmmm what can I say about that!
"This is the end." What does this mean, the end of what?
"I will always love, no matter what one says." So nobody can stop him from loving. Is that eros or agape? I would, of course, suggest eros as people "in love" are notoriously deaf to their loves detractors so in the context of the previous line romantic love makes little sense. Now if he was going to have his way with her regardless of what anyone might say it could be the end of friendship, his reputation or even his life depending on her reaction.
"It is over there, in the meadows". What is over there? Does he only love her in that particular spot or is that just where he caught her in order to do the deed. I would suggest the latter because that was where it ended. An alternate explaination is that she died somehow and is buried in the meadow but
"I have a beautiful friend." would suggest that she is still very much alive so the meadow must be where they lay.
"This is the end. I will always love, no matter what one says." This is a reaffirmation that it is the end of romance and the continuation of life.
Gees I haven't done much literary exposition recently I hope it does not show too much.
