Didn't see it mentioned in any of the threads so I thought I'd bring folks' attention to Finetune's streaming music site. I tried Pandora but it doesn't play very nice with the tablets. Finetune though has site that is optimized for the Wii, which works very well on my n810.

I've been using it to stream music through my home stereo as well as when I'm on the go.

Any other sites that really work well with the tablets?
