Most of my arguments with musicians through the years have had more to do with their attitude about music, or their attitude about their own lives, or their personal responsibility. Music has never really been the big centerpiece of the fight.

Summary

This quote suggests that the speaker has encountered disagreements with musicians, but those arguments were rarely about the music itself. Instead, the conflicts typically stemmed from differences in attitudes towards music, their own lives, or their accountability. It implies that while music is involved, it is not the primary cause of contention in these disputes, but rather the musicians' perspectives and personal values are the focal points.
