CSS DMCA Song – Joe Wrecker
This song came out in 1999 when somebody learned how to decrypt and DVD’s on Linux. The DMCA came out in 1998 making such things illegal.
The DMCA makes it illegal to circumvent encryption, for any reason, without the encryptor’s permission.
Many people viewed this as a violation of Freedom of Speech, so they made T-shirts and this song about it.
The lyrics of this song are the decoding program source code.
