Yahoo is selling personalized, DRM-free MP3s of Jessica Simpson’s new song: “We hope you see the importance of this […] even if you don’t love JS and think that $1.99 is too much to spend on an MP3.” Pretty cool. Yahoo Music’s Ian Rogers, of course, helped found Nullsoft, creators of Winamp, and moved on to Grand Royal, where he shepherded the Beastie Boys onto the internet.
