Kit's Writing Exercise!

I have this thing that I like to do that, incidentally, has to do with writing.
Lately (by that I mean the past year), it's been kind of difficult for me to think up topics for poems, and because of that, I have not written many poems just for fun.
But I do occasionally do this thingy which I will call an "exercise" for the sake of making it sound like a legit writing activity and not just near-plagiarism.
I take song lyrics (that somebody else wrote) and change the punctuation and create enjambed lines to make a different flow and try to make a different meaning or feel of the words by doing so.
One song I have done this to is "And So It Goes" by Billy Joel. I have written it out as such:

In every heart
there
is a
room. a sanctuary,
safe, and
sound--to heal
the wounds______from lovers past;
until
a new
one comes
along.

I spoke to
you________in
cautious
tones;
you answered me with
no
pretense.
And still I fear I said too
much;
my silence is
my
self-defense.

It goes on. I dearly hope this kind of "exercise" will actually help me or other writers in some way, and that doing it here is not illegal.
