Here are the high points in digital music for the past month:

5/1: iTunes 4.8 is released. Now we're awaiting version 4.9 with podcast support, which might actually get me to use the program.

5/4: Cary Sherman of the RIAA called student file-sharing a "pollutant," and the next day a professor at Carnegie Mellon University published an editorial telling him where to stick it.

5/6: The semi-nysterious P2P venture called Snocap, Shawn Fanning's latest creation, completed a licensing agreement with EMI, the third major to sign onto the Snocap bandwagon. Nobody seems to know what's going to come of this.

5/9: Hilary Rosen launched her blogging career at Huffington Post with a salvo against proprietary formats. A new Hilary, or was she hiding her light all those years?

5/11: Yahoo! released Music Unlimited and the Yahoo! Music Engine program. Y!MU is a cut-rate music subscription and music-to-go plan that rattled Rhapsody and Napster with its $60/year price point. the Yahoo! Music Engine is built on some open protocols, and already has many third-party plug-ins, not to mention RSS-enabled playlist sharing.

5/12: The MPAA sued six leading BitTorrent directories specializing in TV shows.

5/18: XM Radio announced it had topped 4-million subscribers.

5/18: KYOUR started its new programming, becoming the first terrestrial broadcaster to derive its entire schedule from podcasts.

5/20: The Canadian Recording Industry Association lost a major court ruling, and tried to spin it as a success.

5/20: The Spanish Recording Industry Assocation pressured a university into firing a teacher who gave a lecture about legal file-sharing applications.

5/23: The MPAA blamed BitTorrent for the roughly 10,000 downloads of Revenge of the Sith that occurred during the movie's opening weekend, despite the fact that the production copy of the movie was clearly leaked by an industry insider.

5/24: Napster surpassed 100,000 ringtones sold in its Napstertones service.

5/25: Bram Cohen, inventor of Bit Torrent, launched the official BitTorrent search engine, courting the Wrath of the Labels, and perplexing observers everywhere.

5/26: Sweden, which had been one of the most liberal downloading nations, passed a new anti-downloading, anti-circumvention bill that resembles America's DMCA.
