If you are looking for sci-fi/fantasy/horror, would definitely recommend the Escapepod (http://escapepod.org/), podcastle (http://podcastle.org/), pseudopod (http://pseudopod.org/) trio. Their webpages also link to some other good fiction podcasts of the same genre. Podcastle's Paper Menagerie (http://escapepod.org/2012/05/17/ep345-the-paper-menagerie/) made me cry.
