In lyrics I rarely use I, sometimes use my and occasionally use me.

When I do the lyric is from the perspective of the protagonist.
This is probably becasue I don't write about my experiences or life as such but may use some experiences to inform a story or perspective.
A very recent piece was written using I quite a bit...the narrative in the 1st person...

Only if you're looking
Yes, only if you look
There's a point
In the distance
I see you aren't there
No, you're not with me.

I don't want to go
You can't make me
I don't care to see
What it took
You're eyes open
Take in the pain
Once again

Only if you're seeking
Yes, only if you seek
There's a point
Just an instant
I see nothings there
No, not you or me.

I don't want to go
You can't make me
I don't want to know
What you know
Eyes wired open
Absorb the pain
Once again

Only if you're looking
Yes, only if you look
There's a point
A single instance
I see you're not there
No, you're not with me.

I don't want to look
You can't make me
It isn't time
It's really not
See it's a crime
Take all the pain
Once again
Once again

Now, the lyric isn't my experience, it is an idea about one person in a relationship analysing a future instead of enjoying a present whilst the narrator rejects that idea from a position of knowledge/perception of that future.
