And while that may be true, what one must realise is that the Beatles kind of started out as a cover band, as a "live juke box" really playing in clubs. Funny thing from the recent Rubin/McCartney interview series: McCartney mentioned that they'd play with other bands the same night and that there was always the risk that another band did a better cover of a song that was also on their set list. So, they started writing their own songs to avoid that other bands would play the same songs that night.
