Women may not get nearly enough playtime on country radio, but they sure do get plenty on Miranda Lambert‘s tour bus.

The country superstar was all about girl power while listening to music on her bus in the early hours of Monday morning. And luckily, the singer shared all her current favorites on social media.

So what was she rocking out to? Songs written and performed by her girlfriends, of course! RaeLynn’s “For a Boy,” Ashley Monroe‘s “On to Something Good,” Brandi Carlile’s “The Eye” and Angaleena Presley’s “American Middle Class.”

“All of us girls are outspoken, and we are who we are and we don’t make apologies for that,” Lambert has told PEOPLE of her fellow Pistol Annies Monroe and Presley.
