Google Music Issues

I have my Music Manager set up to sync with any song I add to iTunes. I've noticed for a number of albums, Google Music is not syncing all the songs in the album. For example Album A has 22 songs in iTunes, but when I open Google Music on my phone or in browser, there are only 11 songs. I've tried signing out of everything, deleting the settings and adding them back again and nothing seems to work. Anyone experience this?

Is there an easy way to get Google Music to match up the songs properly. Some explicit lyric songs get matched up with the "clean" version in the cloud. Other than manually unlinking them and hoping for the best, is there another workaround?

Is there anyway to get music I've downloaded directly on to my phone, to sync to Google Music?
