WFL is just your average EDM song don't get why it's lumped with the other three masterpieces. You also forgot Crazy In Love, people here seem to love that a lot too.
Watched BR, nth times, watched Toxic and TD, more than fives times and watched WFL once, to find out why is there a buzz, but I see nothing so I never returned
Teenage Dream > We Found Love > Bad Romance > Toxic
Bad Romance and Toxic are not good songs. Not really sure why people seem to think they belong in the same breath as such unmatched gems as Teenage Dream and We Found love.
