HTC Sync Manger

So all this syncing was confusing me, but i finally got my music on my phone. However at first on my phone, i clicked the sync now button, and it synced, but not my music. I checked my photo galleries and stuff, nothing synced. All I have on for syncing options in my HTC Sync Manager on my computer is Music, everything else I have selected off. But if my music did not sync, what did it sync :S Dont want to waiste any space
