In order to answer this question, we’ve looked into the following three criteria: total number of albums released, average quality of albums released, number of very high quality albums released.
Looking at the chart below it seems that the artists/bands situated in the top right corner (The Beatles, The Rolling Stones and Bruce Springsteen) make a strong case in order to be considered as the ones with the best discographies, since they have been able to produced a large amount of very high quality albums while maintaining a great level of consistency throughout their career. However Bob Dylan could also rightly be considered for that question given he has produced the highest number of very high quality albums.
For the Beach Boys however it is difficult to see how they could come out well from this discussion given that, despite the large number of albums they produced, they rank the lowest in both categories…
