But how often does trying-to-be-better-and-failing come along and torpedo good-enough-for-the-job?

Would you listen to "good enough" music or watch "good enough" movies? When I ask this, I think, many do. But I don't.

Do you?

No. Sometimes I spend a lot of time and effort seeking out niche genres and digging through blogs and news sites to find "good" music. But sometimes I don't want to put in all that effort, and then putting on "Kind of Blue" or the first Weezer album is "good enough." There is room for both approaches to music listening.
