The Friendship Song by Carbon Leaf from the soundtrack for Curious George 2: Follow That Monkey (actually, kind of a cute movie & chock full of CL songs).
Mairi's Wedding by the High Kings -- not my favorite version of the song; I have a higher-energy version I like better, but still, a good song & the voices of these guys make up for it.
Tell Me Ma by Gaelic Storm
ALB is a lovely lovely lady with some great stuff to say!
