Does That Song Ring a Bell or is it Just a Coincidence?

I included the Chrysta Bell song 'Undertow' in a post I wrote titled -
The Bells Just Keep Tolling, But for Whom?
And I couldn't help thinking I'd heard it before.
It rang a bell to me in other words.
I kept thinking didn't Emma Louise have a song called 'Undertow'?
So I did a search on Emma's songs and found out I was close, but no cigar for me, as it was called 'Underflow'.

And coincidentally I found a symphony piece called 'Undertow' by a guy with the surname of Mackey. 

It just all seemed a bit fishy to me somehow;-)
