Hi Bebe.
One variation I heard recently was that these must be in iambic meter. I think these look better center-aligned IMHO.
While reading this, I guess my nits are that I got a bit tongue-tied and assume your repeat of words is intentional? With so few words to use in this form, I'm not certain if it works? I take away from this that this individual wants to be unique, so offer a few alternates to take or toss as you wish.

I long to hear my song
singly performed like no other
Enjoyed!
