I have been emailing ASUS about this and after explaining the problem about 3 times i get a reply saying:
Dear valued customer
Thank you for contacting ASUS Technical Service
I suggest you to search a third party app which can download songs directly and one can download films like that. Because some format allowed in compter maybe incompatible to your tablet.
Hopefully, you can solve this problem after my suggestion. I wish any inconveniences which coursed by me could be understood by you. If you have any problems, please do not hesitate to contact us.
Wish you have a nice day!
ASUS Service Center
So basically my interpretation of this is, they do not know whats wrong and they cannot be bothered to fix it.
Any ideas now? or im I destined to not have music on my prime?
