It's the same as in books and films: more things than usually happen during a normal real life can happen during 24 hours in a work of art. The process is condensation.

Things like described in usual songs etc. do happen in the real world, but only to few people and even to them not in such close succession.

Books and songs are mostly written about unusual people and happenings. A book about my life, for instance, wouldn't sell at all.

Some gifted songwriters, however, can write about very common events and people and make them the theme of very uncommon songs. These writers are the greatest in my mind.
