A Library of Listening, Made by You

[Commentary] Want to know the real problem with the digital age? There’s not enough to listen to. I mean, what is there, other than your iPod music, your phone, AM/FM radio, satellite radio, podcasts, Internet radio stations, Pandora, Rhapsody, Napster, Slacker, Live365 and maybe one or two hundred other sources? I kid, of course. The thing is, though, they’re all compromises. The free ones don't let you choose exactly what you want to hear or when; the ones that do cost money. But that’s about to change. One phrase should tell you all you need to know about the latest development: free TiVo for radio. That’s the promise of DAR.fm, a Web site that lists every single radio show on every one of 1,800 AM and FM stations across the country. (It stands for Digital Audio Recorder.)
