Anybody ever wonder why Pandora doesn't offer preset mix channels? in other words, when I shuffle Pandora around the house I check every channel so I can shuffle everything. But when I go to the gym to work out, I have to uncheck everything and recheck all of my workout music selection channels. It's a shame that I can't save that selection as a preset so I just click a tab and it switches over to having only my workout channels checked off. Does this sound crazy?
