I normally wouldn't mess with others covering Queen songs but this album is great. It's great for the same reason PR is a great frontman which is that these bands are not trying to do the songs like they are, but instead they re-invent them in a new way.
I will say that the one song that is the most similar to Queen's version is the best to me which is Jason Mraz's incredible cover of Good Old Fashioned Loverboy.
thats not the only one that sounds true to the Queen sound. Also listen to Sum 41s version of Killer Queen, and Rooneys version of Death on two legs. Shinedowns version of Tie Your Mother Down isnt that bad either.
