Rihanna - Disturbia(Best BDSM MV)

I love this song and it surprised the hell out of me when i saw the music video and it turned out to be about BDSM(at least from what i cant tell or just creepy as hell)

ps. i saw someone els post a link like this on here so im going to copy that incase its the proper protocol

How can you tell it's about bdsm? I mean they all have weird clothes but I don't hear anything in the song that says "I like BDSM". If you want a BDSM song, listen to the lyrics of 'Sexy Back' by Justin Timberlake. That's my theme song.
