LimeWire–makers of the file-sharing software client of the same name–was sued last month by a coalition of 13 record companies, essentially for making one of the more popular copyright-infringement tools on the market today. Given the record industry’s willingness to blast on every file-trading service that pops up, this is no big surprise. What is surprising, though, is the countersuit LimeWire filed Monday, which in essence claims that the labels only suing because they’re bloated dinosaurs that cannot keep up with technological innovation, and that they’re only mad because they’re jealous.

In Dynasty terms, this is the “Oh no you didn’t, bitch” return slap at the beginning of one of those catfights that ends up with people getting dunked in a lily pond. So who’s going to end up on top in the end? Given that LimeWire uses the distributed Gnutella network (not the centralized kind that got Napster, et al in so much legal hot water), has actual non-copyright-infringing applications (seriously), and can plausibly deny that its product is nothing more than a tool for piracy, there is reason to believe that it might not be the labels.

On a related note, “Weird Al” Yankovic’s new album Straight Outta Lynwood (Volcano)–which includes his RIAA dis track, “Don’t Download This Song”–is out today. Bloggers have been getting nutty over “White & Nerdy,” his parody of Chamillionaire’s “Ridin’.” This must be the twelfth or so time Weird Al’s gone from fallen off to completely relevant in the span of a week.
