If I'm listening to a moving song I don't think "how exploitative of the writer". There are things that need to be written about and we can't wait forever for them to happen to people who can write effectively about them themselves. Look at the Ewan MacColl radio ballads for example. I can't answer your question about how you square this with yourself as a writer and maybe I'm in a naive minority, but I generally give writers credit for writing because they care about an issue, and admire and value them for it. Especially something like the birth of a stillborn child which is so isolating and still generally swept under the social carpet.
