The original post has absolutely nothing to do with Billie Eilish, and yet you find a way to insult her with only the second reply to the post.
That "untrue" musician you're referring to is an 19 year old girl who writes and produces all her music with her brother in her bedroom and has broken many records including multiple Grammy records.
You don't have to like her music, but the lack of respect on this forum for her artistry and accomplishments is pretty gross.
