Joel Tenenbaum admitted to sharing 30 songs with Kazaa back in 2004 (Kazaa! So quaint!) and was originally fined $150,000 per song. He worked that down to "only" $22,500 per song, but that's still $675,000 in total.
This is the second big victory for the RIAA this month, after the even-more-ridiculous decision that filesharer Jammie Thomas should pay $80,000 per song. But unlike Thomas, Tenenbaum hasn't come out and said he will outright refuse to pay the fine, and it looks like this is a more concrete win for the RIAA dirtbags.
