I'm secretly hoping this doesn't become an official single
Nobody Does it Like You seems like a better choice if they want a song like this (sexy dance and dubstep), it just sounds more adult. Slow Down is good as a starter track, but her follow up to such a massive song lie Come & Get It needs to be picked very wisely, it could set her up for a huge flop less era.
And I just don't think SD can do that tbh.
