Michael,
I have been amiss not to have commented here when I read it the day you posted.
Your rhymes always give a timeless value to your work. (Boulevard matches the cadence of hit so hard; piston & Liston). You are fearless is using this style. It is not enough to make the rhymes, you endow them with the power of driving pistons and punches.
One typo: 2nd line you have "life" - I think auto spell substituted it for "like"
