The song you just cant stop playing???

As a spinoff from another thread, what is the song(s) you just can't get enough of? there are four songs on Tift Merrit's "Tamborine" that I keep on playing
---Good Hearted Man
---Laid a Highway
---Like a Tambourine
---Still Pretending
The new song Bob Dylan wrote for the movie "North Country" is an amazing country-folk ballad that has been stuck in my head since the day I first heard a few months ago. The song, "Tell Ol' Bill," is full of amazing, haunting imagery telling the tale of pain and the scarred resignation that comes with the acceptance of a failed relationship and lost dreams. It is sung from the woman's point of view and ends with:

Tell ol' Bill when he comes home
Anything is worth a try
Tell him that I'm not alone
That the hour has come to do or die.

All the world I would defy
Let me make it plain as day
I look at you now and I sigh
How could it be any other way?

This has to be one of the best written songs of 2005 and one of Dylan's 10 best ever...seriously.
A few from the top of my head...

Both sides now - Joni Mitchell
Concerto de Aranjuaz - John Williams (guitarist)
Girl from Ipanema - Getz/Gilbarto
Walk on by - Dionne Warwick
