there's an artist that i LOVE right now called mindy smith. her stuff's very laid back and definetely...i guess maybe peaceful is the word im looking for.
anyways, there's two songs from her i'd recommend listening to: falling(it's more for if yall have had any trouble or fights...but still really good:P) and also it's amazing.
another good song is from catie curtis, called "magnolia street". i dunno if any of those would work for ya, but it's all i can think of at the moment
