I'm thinking of changing the audio test file that's included with refracta. For all the betas so far, it's been Memphis Minnie's My Washwoman's Gone. I downloaded a few others, and I'd like to know if anyone has a preference. They're located here - http://distro.ibiblio.org/refracta/audio_test/
and before anyone reading this gets their panties in a bunch, they are all in the public domain, so there are no copyright issues. Got them from archive.org which has an awesome collection of old recordings. They also have new recordings, but I haven't spent much time checking those out.
Edit: Today, my pref is Mona, but that may change tomorrow and again the day after that. Your input is requested.
