What makes the Beatles so appealing to me?  It might be that they are the only band that I could listen to for hours on end and not find a song that sucked.  They have countless songs that I find very good.  From the simple tune of "Yesterday" to the transitions upon transitions of "Day in a Life", they are great.  The Beatles have tons of variety in their music.  The great variety is a product of the eccentric John Lennon and the knighted Sir Paul McCartney.  The talent between those two is unmatched by any other musical group.  Paul can sing the purest melody and then yell and scream so loud it makes you cringe.  John has a unique voice and sings brilliantly strange lyrics.
