Query: What can I say they're the greatest rock group ever...

Abbey Road is my pick for the greatest album of all time- and if you don't believe me then you've never heard the musical nirvana that is her B-Side. Arranged by Paul McCartney, is composed of several song fragments that somehow blend together into what has to be the most perfect piece of songwriting in the history of rock music. The A-side isn't shabby either- "Come Together" and "Something" are great songs that would make any album stand out and there's a simple joy to "Maxwell's Silver Hammer" and Ringo's "Octopus's Garden." Indeed either half of the album would be legendary- but the combined effect is an achievement in rock music that has never been equaled, and is all the explanation anyone will ever need as to why the Beatles are still worshipped by millions of fans. Absolutely an assential for any music collection.
