Enjoying the music on this one! I think that the sound is not particularly degraded, though we'll look into that.
I really like the keyboard work on the first half this tune.
In the not-too-distant future, we'll have a pop-out feature for videos, and some other media as well (visual art, and we'll be expanding to creative writing and flash games soon, too so probably those as well).
The main issue with HD videos as I understand is that size is an issue with uploading very large (over 100MB) files that I don't really understand myself-- I think that Youtube lets you use Flash to upload them? We'll have to develop a custom up-loader to do that, I think.
