Hey Mike, no, I've never tried using the feedback function. Sill the new format seems to do a pretty good job of suggesting music, mostly old jazz in my case. It becomes a bit of a loop I get stuck in, where I download some or all of the five or six albums on the home page, end up using most of my monthlies, and so get recommended the same type of thing again. And there do seem to be a ridiculous number of old jazz albums coming out of the woodwork.
