Q: If it were so, wouldn't it be logical for a musician to seek for intense emotion trying to do crazy or unusual stuff, or just travel, see new and interesting stuff, or visit the places were tragedies happen, to get inspired to write sad music? These are just examples, but you get the idea.
A: yes, it is always good to explore and discover. but you don't have to seek out tragedies if that is not your cup of tea
