Yall do realize that the quality of the actual video/audio is waaaay worse when you see it on youtube right? It could be a top quality song and video on the dvd or blu ray, but after its uploaded to youtube and youtube hosts it, it can look like straight shit.
You cant judge the quality of something by how it looks and sounds on youtube. Its so bad that sometimes i'll use my phone to play a youtube song in my car during the day and itll sound like straight shit, and then later the same night ill play the same exact song and itll sound perfect. I think they lower the quality when theres more traffic to the site or something, idk.
