The theory I heard on the Strict Scrutiny podcast is that the 5th Circuit exists to write atrocious opinions on terrible rulings so that the Supreme Court can make rulings that are only 85% as horrible as that so the SC can seem more reasonable by comparison.
Better for what? I only listen to mp3s I’ve got stored on my phone; I use BlackPlayer for that, and I love it. For streaming music purposes… I dunno, I never got into that racket.
