Certainly not! The White Album's very purpose, it's charm, comes from that lengthy, perhaps "unnecessary" material. I mean, for every album there's going to be roughly twice as many tracks as those that end up on there, and this is just The Beatles including those takes. I know many people who dislike "Why Don't We Do It In The Road?", "Wild Honey Pie", "Rocky Racoon", and the other genre-expierimental tracks, and I can never understand why. My only complaint would be, maybe they could've excluded "Revolution 9". (although that's another example of the quirky, expierimental tracks on there) and included for it's length 4 or so shorter tracks.
My favorite Beatles album, one of the best ever. I wouldn't change The White Album for the world.
