After listening many many times I've started noticing that the part that enjoy and makes me smile the most in "Here comes the Sun" is the part after "I can't explain the way I'm feeling" where you start mumbling the melody, and I was quite surprised by that fact because as a songwriter I always thought writing something meaningful brought out more emotions into a song.
right. it does mean something. i've started the section with an instrumental riff, (no words), then jumped into lyric saying "and i can't explain the way that i'm feeling", which correlates together because i've done a wordless riff, then justifying that by saying "and i can't explain", so we've essentially established that we're blending the lyric and non-lyric, while the lyrics are actually referencing this. Then the next 2 lines (which are the ones you are talking about) are entirely in context with this, as we sing another lyricless melody and then explain that we're 'putting it into words', while also doing just that (putting it into words). Also, in addition, the line after that is "send it all over the world" which if you do not think has meaning i would be glad to spend every day of my life in court with you to explain that it does. Also the first thing you said was that this section makes you smile a lot, so i would be curious to know in what world is happiness not meaningful
