are you really suggesting you could put something better in at that place in that song? because a shred fest would NOT fit, neither would adding too many more notes, because the vibe of the song is melancholy and laid back. The notes that ARE played are brilliantly chosen and played sensitively, just because anyone could play it doesn't mean they could have had the taste and restraint to write it.
Playing the right thing in the right place is something not a lot of guitarists can do, many are way too concerned about showing their chops, at the expense of the song. And that need to show technical skill at every opportunity is counter productive. if someone said it didn't qualify as a guitar *solo*, then fine, but as a fill while the vocals take a back seat, i maintain it's perfect.
