From CAT:

Moved the Touch to the basement to listen to it on the stereo overhead while working, and it had an update.  It applied, and Pandora, Internet Radio, and Rhapsody all sounded poor/muddy.  Pops and such, just very poor quality.  I plugged in my other internet radio device and pulled up the same internet radio station on it, and it was fine, so it was the unit not my speakers or the station feed.
