From what I’ve heard, all of those things are true. He dedicates that Bruno song to her and their relationship, and so she wrote this song back to him about him. I’ve had this song stuck in my head since it came out! Great reaction!
It took me watching this video to realise I actually already knew this song (but didn't know what it was called.) It's very catchy, and memes very well. I've never gone out of my way to seek out Miley's music, but I do enjoy her voice.
As a boomer guy, I never before liked anything to do with Miley Cyrus. But, this song is a refreshing masterpiece for today. Her voice is fantastic here, the music is smart, the chorus has groove, swing, and rockin’ soul. In the present sea of musical muck, this song is pure gold.
