Somebody at an apple official forum post a solution (credit goes to Serge Rosenthale). It seems the problem is on the apple side, not being able to synchronize some of the Apple Online Services (Music, TV and Podcasts) with the corrupt user database. There's three workarounds: create a new user profile, reinstall or just clear the databases with a few commands.
1. Sign out of iCloud on your Mac
2. Open Terminal & use the following commands:
sudo -v
Enter Your Mac Password
killall -9 accountsd com.apple.iCloudHelper
rm -rf ~/Library/Accounts
killall -9 accountsd com.apple.iCloudHelper
3. Restart your Mac
4. Open Music App & sign in to your account (You should sign in to your account)
5. Check your TV & Podcast Apps (You should sign in to your account)
6. Open System Preferences & go to iCloud (You should sign in to your account) just activate iCloud Drive
