Cathy Heller of Catch The Moon Music advises, "Give yourself permission to be messy."
I think that's good advise when you ad lib Lyric.
Sing something and see if it sings well, and makes sense too. See if what comes out of your mouth suggests a story you'd like to hear more of.
Sometimes that first Line is just a beginning. It may introduce the Singer-Character with a pronoun, 'I'. It may imply the Singer-Character by conversational nature, addressing himself/herself to communicate 'with' another character, with the pronoun 'you'. That's a direct First-Person form of conversation.
The Singer-Character may address him/herself to the listener, telling us about someone else; the pronoun 'she' or 'he'.
That can happen in Line 1 of Verse I, if you start with a Verse. Some Songs start with the Chorus. Those character 'creations' can happen whatever form you choose.
You are the first listener. You make judgment calls about how the 'conversation' is going to go, who's talking to whom.
Here's a Song idea that came to me in a dream. I've been in a 'fallow' period, not writing, but this dream made me want a Song out of it. Before my judgmental faculties came fully awake, I gave myself permission to be messy, and wrote some Verses, led to the Chorus idea from the dream, did some editing, and a 'final' Re-Write. I enjoyed seeing it evolve as much as enjoying the finished product.
Here's what I remembered of the dream when I woke up:

I had a dream.
I'm walking into a long room carrying my guitar in a case.
A drummer is set up in the back, beyond a circle of couches and armchairs.
A guitar player is laid back on one of the couches, on the left, guitar in hand.
The drummer is sayin', "Well play somethin'!"
I sit down with my back to the drummer, take out my guitar, start playin' E7 and A7, singing, "Taste! Taste of love! Taste! Taste of love!"
I woke up, and played the Chorus and wrote the rest to go with it.

Nobody warned me, about your kiss.
Nobody told me, how much I would miss,
the look in your eye, the feel of your lips,
After The Taste Of Love!
My buddy told me you could set me on fire.
Nobody warned me love could be a liar.
Nobody knows the depths of desire,
After The Taste Of Love!

Taste! I want a taste of your love!
Taste! I want a taste of your love!
Taste! I want a taste of your love!
More of the same's all I can think of,
After The Taste Of Love!

I know you tol' me not to get this started.
You said we could both end up broken-hearted!
I felt the pain in the moment we parted,
After The Taste Of Love!
We got entangled in your twenty questions!
I fell like a fool who never learns his lesson.
Kicked out of school, I came back messin',
After The Taste Of Love!

Taste! I want a taste of your love!
Taste! I want a taste of your love!
Taste! I want a taste of your love!
More of the same's all I can think of,
After The Taste Of Love!

I kissed the Gypsy twice before I paid her!
She said, "You come on like a pirate raider!
I said, "Baby can't we talk about this later,
After The Taste Of Love!
After The Taste Of Love!
After The Taste Of Love!
