Subject: Question : Pickaxe example

I'm reading through part 1, blocks and iterators section.  Lots to
digest here :)
Anyway, there is discussion about implementing a search for songs,
called 'with_title'
Even though the first code example is not the one that ultimately gets
used I think for me it's important to understand it, so I tried
recreating it outside the actual application. I'm getting some errors
and would appreciate some feedback.

Here is the code (I've used some puts statements to see what's going on)

def with_title (title)
myarray = ['Ruby Tuesday', 'Paint it Black', 'Lets Spend the Night Together',
                'Mothers Little  Helper', 'Jumpin Jack Flash']
                         for i in 0...myarray.length

                            puts myarray.length # added in to debug
                            puts 'here is i: ' + i.to_s # added in to debug

                return myarray[i] if title == myarray[i].title
#leaving .title in causes an error

     #about undefined method
                puts 'here is myarray[i] ' + myarray[i]
              end
            end

            with_title('Paint it Black')

If in this line
return myarray[i] if title == myarray[i].title <------ I removed the
.title from the right side of

the equality statement, myarray[i]

I get this back:

5
here is i: 0
here is myarray[i] Ruby Tuesday
5
here is i: 1
