Well, as much as there has been some amazing musical acts, the Beatles are the band that change music and the largest influence to many great artists to follow.
20 number one songs (most by any artist), 13 original albums all number one (no artist has done that), 650 million albums sold (most by an artist), all members in the Rock n Roll as solo artists and as a band. They have 4 albums in the top 10 greatest albums ever. All within 7 plus productive years.
The Beatles catalog, actually only the songs that Lennon/McCartney wrote which is only 151 songs is estimated to be worth 1.3 billion dollars, again a record.
difficult to beat that. sorry Rob.
