Well, no, actually I started this last year by posting a Disco Sucks pic, and was agreeing with gunflyer about the state of current music. In my personal estimation disco isnt much above current music in suckiness, but thats just my opinion since my main love is hard rock and metal.
Oh, I see. Well, Gunflyer is then.
And because this is a music thread: This is (IMHO) as good as disco ever got (although it's technically mixed with Philly Soul or something?)

[EDIT} 4:20 is where it gets really good.
