Sorry but I'm feeling your argumentation is not really about Adam Lambert. I found his cover interesting tbh, as it conforts me that she would have been really good in a rock band. This song can smash as a rock song.
But who really cares about stars, hall of fames, awards or vocal ranges ?
Lana is one of the best songwriters of her generation. She's the one who wrote West Coast. She receives a lot of consideration from the public and from other artists who claim themselves as stans. I love her low and high voices, as it fits so well with her lyrics and her aesthetics. It's something that comes from the heart, you know, you should try.
But you definitely can't expect us to agree with you demolishing her in a forum dedicated to her.
