Subject: Re: |song| Not documented in Pickaxe Book

That is a parameter passed to a block.  It allows the method that
yielded to the block to pass information into the block, which in this
case is a song title (I'm guessing?).

Think of it (sort of) as the method yielding to the block feeding it a
parameter like you would a method call: a value is passed in from the
caller and stored in a local instance to be used in the block.
