I know that there's no tracker for 'zongs busted' at 50/90 like there is at FAWM.
I know that zongbusting is not something to do just for the sake of doing it.
But the zong list is gradually creeping up... and I'm sure there are some good songs which have gotten lost in the shuffle over there.
If you have the time to poke through the zong list and bust one or two in true commentor style, I'm sure the songwriters in question will be thankful. 50/90 goes ghost town way faster than FAWM does and there's less than a week left in 50/90!
