The New Yorker on online music’s potential to replace old fashioned radio:

I didn’t care for a few of the songs, but the experience was much more like grappling with a d.j. than like watching a piece of software operate. I learned about two bands I didn’t know, was reminded of beloved tracks I had forgotten, and didn’t listen to anything I already had in mind. Scotfree’s playlist didn’t last as long as a good d.j.’s shift; the burden is on the user to find other appealing users and more lists, and to build the experience. In some ways, it’s an improvement on the radio model: the number of potentially appealing d.j.s here dwarfs what you might have once found on radio.
