Radio Sonicnet played online radio stations for almost every musical taste. One channel (see at left) was for MTV music. This was "Radio by Daria," with the implication that any music on late 1990s MTV was the kind of music Daria liked.
The Radio Sonicnet website is gone, and the "Radio by Daria" buttons now link to nothing but error messages. However, any alternative rock station online will do in a pinch.
LATE ADD: MTV.com now has its own online radio, and has for some time. Duh.
