I have music on iTunes (Win10) from CDs and also using Apple Music. I want to sync songs to my iPhone from library Music Settings for iPhone on iTunes shows iCloud Music Library is On How to transfer songs from my PC iTunes to iPhone? Frustrated

When you use iCloud Music Library as part of either Apple Music or iTunes Match the intention is that you enable iCloud Music Library (aka Sync Library) on the device, and that all music you add to your iTunes library becomes available to the device through the cloud, where it can be streamed, or downloaded to the device for offline use. This is used instead of direct syncing with the library over USB. I don't think Apple Music content can by synced from iTunes even if you disable iCloud Music Library on the device. See Identify cloud status icons in your music library on your Mac or PC - Apple Support and make sure that none of your music is waiting or has some other error. You can use the download icons on the device to download tracks, albums or playlists.
