So you happen to be leisurely browsing Youtube and you happen to spot something interesting, in the related tab on the right, so you decide to click on it.

...and so you end up watching something like this:

Please share your strange findings. Since this is a music forum try to keep them music related lest this thread be overrun with funny cat and dog videos.

Sorry if there is already a thread like this...

 

not exactly what you were after:
once when looking for a song by Emerson, Lake & Palmer i came across what i was looking for, but got a bit extra.
the video uploader set the song to insanely over patriotic american images. flags, eagles, statue of liberty, etc they were all there. also all the people who commented addressed each other as brother, and said weird white powery kind of stuff to each other.
it quickly became apparent that this youtube page was being used as some kind of extreme right wing american meeting ground!
when i pointed out that E,L&P are in fact a British group, i was impolitely told to go elsewhere.

 

You should have linked to this in your comment on there
