... the remasters and The Beatles: Rock Band.
Excerpt from the former:
An enormous effort was made to stay true to the original mixes, so there aren't going to be any easy revelations for Beatles fans. Instead, these albums sound deeper, richer and fleshed-out. The buoyancy of "Something" becomes more comprehensible when you hear clearly Paul McCartney's nimble bass line. You knew that "Twist and Shout" featured one of John Lennon's most visceral performances, but here you can feel his vocal cords shred. The horns on "Good Morning Good Morning" roar, driving the song in a way you may not have noticed before. Lennon and George Harrison's guitars on "You Can't Do That" sharpen to a gleaming edge.
And the latter:
But thanks to richly detailed and artful graphics — highlighted by the psychedelic images that pop up once the Beatles quit playing concerts — it is the most refined music video game ever. From the Beatles’ facial expressions to the signs at Shea Stadium, there’s enough verisimilitude that it’s forgivable when no animated Eric Clapton turns up for “While My Guitar Gently Weeps,” or when cartoon Ringo is shown playing drums on “Back in the U.S.S.R.” (it was really Paul).
