Song meaning of Already Gone by Eagles

Well, well, well, look at Mr. Ego over here! This song "Already Gone" by the Eagles is like a dramatic breakup anthem on steroids. So, let me break it down for you, honey. Basically, our friend here is strutting around like a peacock, telling whoever dared to doubt them that they are already out of there with a mic drop moment. And oh, don't forget the classic "eat your lunch all by yourself" line – take that, Karen! Then, they go on about some cryptic letter and staring at stars which I'm pretty sure is just a fancy way of saying, "I'm too good for you, bye Felicia." And in the end, they just keep singing about being "already gone" like they're reaaaally trying to convince themselves. Honey, we get it, you're gone, now go hit the road Jack, and don't you come back no more, no more, no more!
