Does anyone still have the World Weather Theme from 2006-2007? There's a full version here on YouTube but it's seems that the original was compressed and turned out to be of quite low quality with all "variations" on YouTube sounding much worse compared to the shorter version here that was broadcast in the early days on CNN.
I patched that together over several months from a medium quality RealPlayer stream of CNNI. That's the highest quality I ever found. I don't think CNNI was even available in stereo sound at the time anywhere.
