In re: MOG, and Anne Briggs

It's kinda crass to criticize something free, but I've grown weary of Pandora--sound quality's not very good and, in particular, the music library's very limited--unless you constantly tweak your stations, you get frequent repeats of songs. Ergo, I bit the bullet and paid the $4/month for MOG, which is quite amazing. Very good fidelity and a fantasticly broad collection--even with my obscuro tastes they have probably 80% of the albums I searched for, plus a ton of live stuff, rarities, etc.
Which (rather randomly) brings me to my current obsession, the 60s English folk singer Anne Briggs. She sings traditional (and traditional-sounding original) stuff, largely a capella, though she's also a good guitarist. Known (if at all) for writing the Led Zep song "Baby I'm Gonna Leave You" (conveniently stolen by Jimmy Page). Now a capella folk music may not be a genre you crave, but this stuff is incredible--haunting, funny, etc. Can't stop listening.
Enjoy your Sunday, y'all.
