Relax, Slyde, they found it.

From Alan Absor:

I hate to report this, but there does indeed seem to be a problem with some
bard songs. We're working on fixing that right now.
But just so you know, the casting timer is intentional (and not the problem
with the spells). It just seemed to make sense to give bards the same
information about their casting (singing) as other casters.
