There used to be a site that allowed you to stream music from all the games, sort of like a virtual juke box, but it's no longer available. Does anyone happen to know a site where you can get the C&C1 and Red Alert music?

Also, there used to be a Lucas Arts Soundtrack site that had a lot of stuff for download from their games. Does anyone know where that's at?

I don't know if you mean his official site one, but that's got all/most of C&C tracks

That site's not it, but it servers the purpose. Although I wish it'd let you skip ahead in a song and organize them by game in a better way.
