It's like they know me

Listening to the internet radio station http://www.pandora.com while I work. You plug in the names of songs and/or artists that you like, and it uses the Music Genome project to select more songs that it thinks you'll like. You get the chance to vote thumbs-up/down to refine the choices.

The best part is clicking on the key that says "Why is this song playing?" According to my current selection, my previous choices have indicated that I like "emotional male lead vocal performances."

There's a reason why I've named this virtual station angst-rock.
