Rankings and "do NOT play" suggestions

[DodgerMatt]

Is there some protocol for suggesting certains bands/songs NOT be played? I don't mean to start a thread where people jump in and mention all the bands they hate, but there are some that I've heard on AM (one notable--Godspeed You Black Emperor) that I find absolutely nothing good about about and turn off as soon as I see them in the queue. Especially long songs that are really bad (synonymous with GYBL stuff) should require at least three people within an hour to request them before they are entered in the queue, only to be played in the wee hours...or some other restrictions.

Sorry to rant. But is there some way to set up a ranking system for registered members? I am constantly hearing really good music from bands I had only heard of before, or from bands entuirely new to me. If I had a chance to rank these bands/songs and found that others had ranked them similarly, I would get a real good idea of the quality of some of the songs in the queue.

Thanks. Great site BTW.
