I've been searching around the forum for this request and I can't find it, so I'm making a statement for myself 
I've noticed that in the osu! beatmap song folders, the video and the song is separated, therefore we won't be able to get a whole music video @ MV unless we combine it ourselves. In osu!, the spinners and hit circles interrupt the video and the song itself at times.
What I'm suggesting is a mode that cancels all the spinners, sliders and hit circles, and leave only the song and the video within the game, for viewing purpose only.
