Quick Take: The thing we love the most about the Audio Lunchbox service is that when you pay for digital music, the company provides songs that can be played on any digital audio device, regardless of DRM. Audio Lunchbox's songs are all in the MP3 codec and OGG formats--your choice, as the ZIP file you purchase typically contains both, as well as album art. The only problem with such a beautiful, open approach is that it scares away major labels and many indies, who license their songs only to services that wrap their tunes in DRM protection--à la iTunes Music Store--limiting playback to certain devices, among other restrictions. That's why you won't find tunes from Outkast on Audio Lunchbox, though the service lists more than 100,000 songs from indie artists such as Bad Religion and Bettie Serveert.
