Warner Music Group (WMG) is suing Seeqpod, the most popular of a new breed of music search engine/players with a new twist on the original Napster strategy -- rather than let users download copies of other people's MP3s, it lets them listen to streaming MP3s hosted on other people's websites. The last numbers we saw pegged the engine's catalog at 8 million songs, and it's got a slick interface, quick response time, etc. Whether it's legal is a different matter. (Silicon Alley Insider)
