Here gathered here all 27 tracks of the Beatles that were No. 1 on both sides of the Atlantic when it is not 2 sides at once. This is of course official rankings: Billboard for the USA and "Top Of The Pops" to Britain. Obviously some songs like "Please Please Me" was also No. 1 but it was unofficial rankings such as the famous Melody Maker, English musical journal. "Please Please Me" was only second to Top Of The Pops. Aside from Elvis Presley, who else could boast collect as many tubes of this quality? Not only the melodies cling but the arrangements still have that small detail that makes the difference between an ordinary and a Beatles song. This is the leg of John Martin in collaboration with the group that was able to turn what might look like a great song by song. Examples abound: the dissonant chord guitar intro in "A Hard Day's Night" is the song. The feedback guitar sound in "I Feel Fine" introduced the piece in a masterly manner. The sound effects of "Yellow Submarine", voice tampered "Paperback Writer" and the introduction of drums reverberated in "Come Together" are all innovations that surprise even now, when all sounds become increasingly standardized and specially designed for the sole purpose of making massive sales. The titles in chronological order clearly show the evolution of the Beatles who have never left trapped in a stereotyped style; but rather have always been at the forefront of the latest music trends. In conclusion, this compilation of No. 1 is the best introduction to the Beatles since it only contains classic tracks. For the rest, "Michelle", "Girl", "Sgt Pepper", "Revolution" and many others, they can be found in the famous compilations "blue" and "red"; but these titles have never been No. 1 or so other artists. The 27 remastered titles here already give a foretaste when all the band's discography will be.
