Won't accept single songs/palylists in iTunes after os3 update

Question

Once iPhone is synced, I go to music in iTunes and try to drag just one song over or a playlist and the phone won't accept it.
I went into settings and set the music to automatically sync playlists and it will add the music that way.
When I updated the OS3 all music and playlists were removed from the phone. Everything else was there, apps, images, pictures I took specially from the phone itself, but alas no music.
Is there anything I can do. I searched and found a lot of other issues with this update but nothing about music.
I have not changed music formats, updated anything else (outside of the iTunes 8.2 upgrade). Actually the only change is I restarted the computer today because of loss of power.
Any ideas?

Answer 1

I let the sync fully load on one playlist. Once that was done I unplugged and powered off. Power on and sync again, clicking the manually chose music and video in first pane of setting window.
After that it allowed me to load any song. Not sure why it did this after the update but maybe a software glitch? Resenting and syncing may have done the trick.
