Honestly, I do not have a single favorite Beatles song. This is something that is very much affected by the mood or environment I am in. This second, I would have to say it is “Something,” but if I were in a more upbeat mood it could be “It’s All Too Much” or “And Your Bird Can Sing.” Man, those guys could write a tune.
Dependant on mood my favorites are All you need is love, Norwegian Wood, A Day in The Life, Something, and Nowhere Man. Right now my favorite happens to be Something.
I agree with danzig, I can’t have just one favorite Beatles song. To limit the best band ever to just one song would be insane. At this moment, iTunes has shuffled “Dear Prudence” my way and I must say that it was some of their best work. It seems that I can really never over-listen to any of their songs.
