I don't know if anyone else has posted this, but "Big Finish", makers of audio plays from Sherlock Holmes, Robin Hood and Doctor Who to Dark Shadows, Stargate and The Avengers (John Steed, etc.) has some free audios you can listen to and download legally from Soundcloud. Log In. It's just a few Doctor Who ones and a funny Sherlock Holmes Christmas one, but it's pretty awesome even for those who just like radio dramas. I particularly enjoyed "Cuddlesome", which is a story about some alien furby-like toys coming to life and attacking those who abandoned them as they grew up.
