Google Play music issue

[illmatic96]

So i have an issue with the google play music app. Im on jelly bean 4.1 with the latest version of the play music app. I noticed in the play music app some art work wouldnt show up so i would assign the artwork with an app. Once i assigned the artwork it would show up on the coverart app i used to assign it and also in the default samsung music player, but not the google play music app. So i gave up. Now today i noticed that after about 2 weeks of these albums sitting on my sd card without the artwork showing up, some started to finally show up, but some random ones artwork which had always been there has dissappeared!! All songs are on my devices sd card not in cloud storage as well.

I have, tried doing that and nothing happened so i completely quit the app relaunched and then refreshed and still nothing.
