"Legendary Lovers" is the only song, bar "Roar" and "Dark Horse", that really stood out for me. The rest seem to just blend into one another and don't seem to be very eventful.
The first part of the chorus to "Legendary Lovers" is easily the best thing on the album (that we've heard so far, but I doubt anything will top it). It's very "Crazy Kids/Last Goodbye" and I like that. Should be a big hit for her.
