It was of course a hard choice, but I picked I Feel Fine. I just love that song soooo much because of the amazing solo and the amazing guitar all throughout the whole thing. The End came pretty close, though.
And while I'm talking about it, does anyone else notice that at the end of I Feel Fine where it's fading out there's like this weird noise that kind of sounds like a dog barking? I don't know if it's just me, but if you turn it up loud, especially with headphones on, you can hear it perfectly clear.
