Last week I found a batch of forgotten Minidiscs, and on one of them was a recording I made of XM Watercolors (channel 71) from 23 February 2007. The first time I got to hear the service was at a restaurant a few months earlier. At the time of this recording, some XM channels were available for free online from MSN. That is where I got this. The files can be found here:
