I prefer Jango. It lets me build a station with only the artists I want to hear. I can also select individual songs I never want to hear, songs I want to hear sometimes, and those I want to hear a lot.
Maybe a bit off subject but can anyone tell me where search information in IE7 is stored. For instance, if I go to Google and type in a search phrase that info is stored somewhere because the next time I start typing in the search box a list of possible matches show up.
