-- Lala has some pretty incredible sale prices for the Top 200 Albums of the 2000s feature at Pitchfork. Radiohead's "Kid A" is $1 (the #1 album), Broken Social Scene's "You Forget It In People" is $1.99 and Daft Punk's "Discovery" is $2.99. Most titles are either $5.99 or $6.99. Radiohead's "In Rainbows" (different label and distributor than Kid A) is one of the handful of titles going for the not-so-special price $9.99. Take this sale, the U.S. debut of 7digital, the innovations at low-price store Amie Street, Amazon.com's continued bargains and the always inexpensive (if you use all your credits) eMusic, and what you've got is a renewed focus on price at digital retail. But unlike a permanent price decrease for all titles (which many argue would be a boon for sales), these price wars are more like brief, isolated skirmishes that will make it difficult for onlookers to assess if sales spikes could be maintained in perpetuity.

-- Did Viacom find a smoking gun in its copyright infringement against YouTube? CNET's Greg Sandoval reports that internal YouTube emails offer evidence that managers knew about and discussed unauthorized content hosted by the service. Such actual knowledge of copyright violations would be in violation of the DMCA's "safe harbor" provision. It's a long article but well worth the time. (CNET)

-- The New York Times says YouTube will announce today an improved content identification system that will help media companies upload their reference files. The changes will allow YouTube's Content ID technology to identify video clips almost immediately after a live program or event. (New York Times)

-- From the Billboard event at CTIA yesterday, a post on EMI Music's upcoming iPhone app due next week. "You'll have to discover how to interact with it," said senior VP of digital marketing Syd Schwartz. "You'll learn that if you shake it while you're playing one song, for example, 'this' happens; if you swipe it during another song, you get another animation." (mocoNews)

-- Dutch collecting society Buma/Stema has a two-step plan to collect money for embedded audio on Dutch Web sites (a blog that hosts a YouTube video, for example): an audio detection technology to spot the copyright audio and an annual license for the host. The cost of the license comes from the Fair Play Calculator. A dozen embedded audio streams would set a person back a few hundred dollars. One has to wonder if the costs of collecting licensing fees from consumers will exceed the revenue it generates. (TechCrunch)
