Songs that get all meta and mention 'this song' in the lyrics

Edward Bear, “Last Song”

It's the last song I'll ever write for you
It's the last time that I'll tell you
Just how much I really care
This is the last song I'll ever sing for you
You'll come looking for the light
And it won't be there
But I love you
Oh yes I do
Yes I do

This is just a long song, it ain't no poem
Leave the lights on till your baby gets home

Brinsley Schwarz, “Love Song”

This here is a love song
I gotta get back to my baby's heart again
This here is a love song
And I'm gonna sing it till I get back home

Which is also mentioned on this similar thread: Songs that are aware of themselves

Barenaked Ladies, "What A Good Boy"

I couldn't tell you
I was wrong
Chickened out grabbed a pen and a paper
Sat down and I wrote this song

Tom Waits, "Hold On"

Down by the Riverside motel
It's ten below and falling
By a ninety-nine cent store
She closed her eyes and started swaying
But it's so hard to dance that way
When it's cold and there's no music
Oh, your old hometown's so far away
But inside your head there's a record that's playing
A song called "Hold On"
