Issues Downloading Library (Play Music)

I'm having a problem getting all of my library from Google Play Music to download to my laptop (Macbook Pro running 10.9). It says I have about 6,100 songs uploaded to their service, but only ~4,400 will download back to my laptop via Music Manager since I wiped my hard drive the other day.

It seems to be selective in what it downloads for whatever reason, like tracks 2, 7, 12, and 14 from one album but not the other tracks. I'm just having a hard time figuring out what could be causing this. If anyone has any suggestions I'd love to hear them. I'm just trying to get everything back onto my laptop for syncing purposes with my phone.
