Is it possible to add a song on my iTunes Library on the Mac, and sync it to my iPhone through iCloud? Seems like iCloud is not for songs that I ripped from CD and add to my iTunes Library?

It seems that I have to hook up the device one by one, the iPhone, the iPad, the iPod, and then drag the song from the iTunes's Library or Playlist to that device?

I tried that on the iCloud on my PC and it seems to be able to sync the bookmarks, Outlook data, Photos, but not for songs.  Is that correct?  It works for songs that I purchased, but not for songs I ripped from a CD myself?  I haven't tried that on the Mac yet as I am still running Snow Leopard, but upgrading to Lion still might not be able to sync the songs I ripped from CD through iCloud?

iCloud in Control Panel of Windows 7:
iCloud does not handle music at this time, and likely never will since that content is handled by iTunes, although only for purchased content:



Because purchased content runs through Apple's servers, it's easy on them to just push the newly purchased song to any device connected to the respective Apple ID yet still retain control of the media, so to speak.

As for iCloud on OS X, it only includes a few more features over the Windows version, but none of them deal with music:



I don't doubt they could add the functionality, but it might ruffle feathers (RIAA) and certainly put considerable load on their data centers.
