The proper way to propagate information with exceptions is using the

I'm not entirely sure that this is the proper way to propagate the
exception. I see far to many people catching exceptions to print them, or
worse, to print a generic, useless message like "an error occurred".

You misread me, I was referering to passing *information* with exception
(in other words, use the exception attributes). In the example I gave,
the exception has the songId value responsible for raising the error.
I totaly second your opinion on how poor the above handler is (hmm not
sure about this grammar construct, it sounds like a Yoda sentence).
