Found out that, in addition to Public Enemy's Fear of a Black Planet and Nirvana's Nevermind, Sonic Youth's Daydream Nation has been added to the Library of Congress' National Recording Registry.
There is a delay of 10 years before recordings are considered, so it'll interesting what American electronic music makes it. Especially when the field is so overwhelmingly European. (It'll likely just end up being Beck or Moby, but I would love to see NIN, Matmos or even Ministry on there.)
p.s. Oh, Plastikman would work too.
