This was such an eloquent statement on what not only she, but every artist thinks. Kudos to Gaga for that.
All artists want, or should want, to evolve and although leave a legacy, they want to move on. This is why Rihanna, for example, does not reminisce in her past hits like Umbrella and We Found Love. Those two songs are their own peice of art and will never be recreated for any purpose or with any intent.
With that said, I hope that Gaga continues to push forward with this purpose in mind. It's what makes her such a industry staple. There was nothing rude, angry or meltdown-like about this statement whatsoever.
