song

She Loves You by the Beatles.

I have determined that analyzing  poetry is not my strong suit. That said, I think a couple of these "techniques" I found might be a little shaky, but I think that's mostly left to how its interpreted.
I found several different techniques in this song, but the most unusual one I found was anaphora. When I think of anaphora, I usually think of a pledge, or an oath. "We will do this. We will do that. We will honor this. We will pledge to do that." And et cetera. But this anaphora is smooth, very different from the harsh anaphora I'd seen before. It's the repetition of the phrase "she loves you" at the beginning of every other line in all but three verses, when it say, "She loves you/and you know that can't be bad/she said she loves you/and you know you should be glad."
Another thing that goes on is sibilance. This occurs every time the words "She says she loves you" are sung. (She says she loves you). There is a hyperbole when they sing "she almost lost her mind." I know this doesn't count because it's end rhyme, but the rhyme scheme is ABAB for all standard verses and the chorus. the intro, bridge, and conclusion don't follow this pattern.
The last two things are the ones I consider to be really shaky. This is because it is left entirely to how a person looks at these words. The first is euphony in the verses. In verse one, they sing, "You think you lost your love/Well I saw her yesterday." I hear this as euphony because of the "oo" and "eh" sounds that are repeated and because of the sibilance in line one. And although the words themselves can be viewed as sad, the syllables are smooth. And the last thing I noticed was personification. This is when they sing, "Pride can hurt you too." I view this as personification, because I think they're referencing the fact that the person who they're singing to hurt the girl. I think that it's a karma thing.

But then again, its all based on the connotation.
