Line Spacing

I have done a lot of lyrics and I'm using Calibre to convert them to E-books. I have tried every option I can think of using but I can't get them in the layout I want.

This is part of a poem I wrote for an example of what I mean. I type the lyrics like this:

My heart is like a rose
Your heart is like a shower of water
Which feeds my heart
Love is the feeding power
Which fills life with joy
And makes things grow

But the best layout I can get when adding them to Calibre is this:

My heart is like a rose Your heart is like a shower of water Which feeds my heart Love is the feeding power Which fills life with joy And makes things grow

Is there a way to sort this out please?
Thanks.
