Heartache can do a number on you. It often leaves open wounds and scars, those markers that serve as constant reminders of what once was. With “Things Don’t Have to Change,” duo Megan and Shane work through Megan’s heartache, sifting through ash to find what’s left of her broken heart. “I don’t want to hold to the heartache or the pain / Yes, some things are different, but some things don’t have to change,” sings Megan. Enlisting Lillie Mae and Brit Taylor, the song flutters away into the stratosphere. It’s the sort of star-studded collaboration we’re not likely to forget anytime soon.
