Pandora is a Flash-based front-end to yet another music recommendation service based on something called the Music Genome Project. Basically, you start by inputting a song or an artist, and Pandora suggests other songs, which you approve or disapprove.
I have pretty eccentric and off-beat tastes and was quite pleasantly surprised by the way Pandora handled them. It recommended some really pertinent stuff. You can save different « radio stations » for later enjoyment. Tip: although the site is limited to US residents (due to licensing issues), all you need to do to create an account is enter a US zip code.
Thanks to Pamela for this one.
Update:
I have a really shitty and monotonous job to do today, so I created a B-52’s radio station this morning to help keep me awake, and have been working to the sound of the mostly quality music that has been streaming ever since: The Kinks, Stranglers, Devo, Nico, Blur, Sparks, more B-52’s, although it did screw up badly once by bringing up a…Celine Dion song! Even so, nicely done.
