*Hi Roujan, err what exactly is your point? A lot of people are fans of the beatles, but there is still no way to class a band as "greatest act ever" since that is purely an opinion. Not to mention even if they could be classed as "greatest act", the title would only stand within their own genre of music. For exaple I am a hiphop producer and while I appreciate and listen to all styles of music, The Beatles would never even enter my top 100 favourite bands. So you see, while you may feel that they are the greatest act ever, I do not, therefore they will only ever hold the individual records that they have achieved.
