For those who wanted to see, here's the percentages I calculated (sorry it took forever, I can do the rest if people show interest but for now I'm stopping with these)

Our class has created an estimated:
4 songs per woman
142 songs per man

1035 stories per woman (one 10,000 estimate skewed it a little)
141 stories/man

843 poems per woman
29 poems per man

11 dances/woman
.8 dance/man

8 videos/woman
17.5 videos/man

One of my main motivations for doing this survey came from something written a leaflet in my first Propagandhi album:

"Go look at your record collection. Your television. Your bookshelf. If you're like me, chances are that between 75 and 100 percent of the artistic expression you consume is made by white, heterosexual, middle to upper-class males. Maybe we should be asking ourselves: AREN'T WE BEING CHEATED?? White heterosexual middle-class males make up a miniscule portion of the people on this planet! Think of all the emotions and thoughts we're missing! The incredible variety of voices that are lost due to our society's sexism! Feminism's primary concern is social justice, and wrapped up in that concern is the potential of every individual to be more complete, more informed and, well... happy."
