well, there's no harm in comparing two different bands. you could say AC/DC and Led Zeppelin differed in song composition, but there's still a mean somewhere there. so there's no harm in comparing the beatles with cueshe, so long as there're some factors that can link them together.
on the other hand . . . criticism is one of the guides to progress. can't make the music better if you don't sort the swill from the five-star alcohol.
