Receive an error when trying to migrate and not all test passed

When i was trying to check migrations using 'python manage.py make migrations songs', it was fine. But when i tried to migrate it 'python manage.py migrate songs', i received an error

RuntimeError: Error creating new content types. Please make sure contenttypes is migrated before 
trying to migrate apps individually.

And when i tried to test the module, not all test passed. But i don't really understand the error here and have been trying to find a solution for a very long time.
