It'll definitely get to at least 100M, but I don't think this is getting anywhere close to 175M. That puts it in the Compton/Bohemian league of music biopics and I don't think Elvis really has the same cultural touch. Obviously everybody knows him, but I feel like, at least for a lot of people around my age, he's not really somebody people obsess over or listen to in their spare time. When I was a kid, outside of Lilo & Stitch, pretty much every cartoon had Elvis jokes or people impersonating him to make fun of the guy.
Queen and NWA's music is both something fun to jam to in surround sound and their stories tackle relevant and topical issues that relate more with younger people today. If anything, there's been a lot of discussion about Elvis and his cultural appropriation, which will probably lead to controversy, whether you agree or not. Austin Butler will have to really deliver in the role to help this get to 150M+
