Can anyone find the music videos with the best like/dislike ratios (I mean the smallest dislike bar against the blue bar below the video on YouTube). 

Calculate the number of likes divided by the number of dislikes to get a number, and the bigger the number, the smaller the dislike portion. 

Rules:

The video must contain an actual song, but it doesn't have to be an official music video, audio or lyric stream.

It must have at least 1 million views and at least a month (30 days) old, meaning published to YouTube 30 days ago.

Well done to anyone who finds a video with 1 million views and NO dislikes!
