Apple ipod

Music iphone … i can not add music in various iTunes libraries! Help me?

My attempt to add music from my notebook on my iphone and it worked fine … and he was in [[manually manage music and videos]] and was synchronized with only one part of the music on my computer laptop … but I moved and tried to add more music to the mainframe and had [no mark [Manually manage music and videos.]] so review it and synced, but all my music is gone! HELP … I love my music please please in advance – Thomas

You can synchronize with a library with an iPod at any time, if you need to have all your music into a library and a fair use. If computers and laptops are net, is a way to use a library between the two, three, or more, let me know if you know how.
