Can my iPod Touch sync to RealPlayer or the Amazon Cloud Player?

My Dad recently erased all of my music files off of my new computer. Fortunately, I had them backed up on the Amazon Cloud Player. I found out that the Amazon Cloud Player can transfer all of my songs to Real Player, but not to iTunes. All that I care about is syncing my iPod Touch to one of these places. (And getting new updates as well) Can I sync to either of thse places so I don't have to erase all of the current data on my iPod?
