I found a third one that isn't as positive about the whole album, but rates it 4 out of 5 stars as well. I posted that one in the review thread as well!
Now if the reviews that count for Metacritic can just continue in that vein...
There will be many who absolutely hate Warrior, with its insistence on turning the volume up to 12 and wallowing in baser joys. There will be people who won’t even listen to it because it’s Ke$ha, and frankly that’s their loss. Others will love it for its balls-out attitude, seen not nearly enough from any artist nowadays let alone a female pop starlet, and willingness to fall on its face in search of something new. It's undeniably ******* insane, but Warrior is never dull, always fun, and frequently a thrillingly unpredictable ride.
