Your video, Awesome - Joan Jett & the Blackhearts - I Love Rock N Roll, has made it into your personal Highest Rated Videos listing. Congratulations on a job well done. For you contribution you have been awarded 1 Power Point.

I am LOVIN' your unsifteds right now. From Neon Fever to the cousin-loving rock-n-roll pioneer, this is a banner submission time for you. Farhad at his best. Thanks for the great vids.

I have been exposed to so much interesting and great music on the sift. I'd hate to have it put through someone's 'taste' filter. Hell, even some of the pop stuff is so bad, or so egregious, that it bears watching; Briney's "I Love Rock and Roll" was so stunningly bad that I had to watch it twice. Mind you, that is a lifetime supply and then some.

BTW, y'all know the *quality thing doesn't work yet, right? Not trying to discourage anything (and I think it is a very nice gesture), but so far the policy isn't implemented.

lol i've only attempted it on easy with joan jett ... fun game!!
