What Do I Not Understand About Videos of Records Playing on You Tube?

Can someone enlighten me about this phenomenon?
Every time I search for video of any reggae, Dub, rock steady and ska stuff I find heaps of videos of records turning on turntables with shite sound quality. Is this not absurd? I mean, the video quality comparatively is better than the audio quality. Is this not just a weird form of vanity being expressed by foolish people?

It really clutters the searches and crowds out the good video material. You know, cool stuff that people video taped from TV in the 70s, public domain stuff, amateur vids of significant people etc.

I suspect this is a circumvention of the ludicrous action taken by the search engines due to monumental force exerted on them by the mafRIAA and it's affiliates - so now that you can no longer search for audio using Google, Yahoo etc. (but there is always Baidu.com) you can search for the video with audio attached. And if you know what you are doing you can rip the audio. But isn't this just a huge wast of time, disk space, effort? Especially if the audio is rubbish?

I'd like to link some cool stuff here and not have to waste time on this.
Comments please.
Excuse what I think is justified indignation.
Is there a suppository for this repository of shite?
