This is a fun album. Freddy Mercury is amazing of course. They all were good singers but I don’t know why you’d want to Brian May sing lead on any song with Freddy Mercury in the band. Brian May is a great guitarist I love his tones. Killer Queen is such a cool tune. Stone Cold Crazy is a cool riff it’s almost like proto thrash metal. I’d give maybe a 4.5 because I’d probably skip over a tune or two if I was listening again
