Well, download took longer than expected :).
Anyhow, here's a sample from the csv file:
filename,text,up_votes,down_votes,age,gender,accent,duration
cv-valid-test/sample-001224.mp3,but i felt miserable watching him wither away like a shriveled dandelion,1,0,thirties,male,england,
Not sure how some of these are being populated, but yeah; there's several additional folders including invalid mp3, a splintered train set (not sure how it was selected) and a test set folder.
Here's the README.txt. Looks cool! Have happy hacky fun! :)

Interestingly; many of the 'invalid' mp3's are actually (mostly) correct. Listening to them is interesting to guess as to why they were downvoted.
