Instant Star » Google Music song upload problems

Is anyone else having issue uploading music that meets all the requirements?
I have a lot of first songs from albums not uploading to Music. They all meet the requirements, and the rest of the album uploaded fine. Just not the first song. Not sure why it's doing it, but it's quite often.
I also have full albums that won't upload that won't upload either. Quite a few of them, all meeting requirements as well.

I didn't find the right solution from the Internet.
