MIRANDA LAMBERT has released a new song "Sweet By and By".

It's her contribution to the "Southern Family" compilation album, which, you may recall, is how she met her boyfriend ANDERSON EAST!

"Southern Family" is such an interesting project!  A producer asked his favorite artists to contribute songs about how they grew up, their families, and all the things that make them who they are.

Other artists on album include Zac Brown, Chris Stapleton, Jamey Johnson, Shooter Jennings, and Brandy Clark.  "Southern Family" is out March 18th.

Here's Miranda's song -

What do you think?  I think it's really sweet, and a different sound for Miranda.
