The Internet's billions of radio stations are a boon to music lovers, but it's hard to find what you want to hear in a medium where hitting "scan" only serves to digitize an image of your buttocks. For browsing that's a bit more exact, check out Tun3r.
Tun3r organizes the ever-expanding galaxy of Internet radio via an intuitive 3D "Seek" system, making it spin-the-dial simple to navigate towards someone who'll play Loverboy's "The Kid is Hot Tonight" with the frequency you demand. Click on any of the station thumbnails to preview a streamed sample and browse recent playlists, station details, and a snap of the homepage -- a quick glimpse'll determine if it passes your most important litmus test, no Cher on the Homepage. If you're looking for something specific, the search function runs through all the aforementioned information, helping you locate particular songs, artists, genres, or apocalypses (e.g., William Shatner's haunting cover of "I Want to Sex You Up").
Once you've picked your poison, click to push a hi-qual stream to your default player (iTunes, RealPlayer, etc) for a listening experience even more engrossing than your gloriously pixilated tush.
