So I havnt been on this site for 2 years now. I just found it recently due to facebook, and I was reminiscing about old times. Then I go to click on the videos, and all the artists removed their videos from my site..... What the heck!!! They were for the enjoyment of myself and they took it away? Danm them. Ah well at least you get the gist of the videos, and can look them up for yourself.
