If I recall, Pandora has a relatively gentle onboarding. You can start a new station without being logged in and it's not until you interact with the site further (to rate, skip, etc) that they start pester you to sign up. I don't know how their conversion rates are, but I appreciated being allowed to at least get a brief feel for it before handing over my contact info.
