fix for NoReverseMatch error after integrating django package (django-audiotracks)

Question

I'm relatively new to django.. I'm trying to integrate the audiotracks package with my project. I'm trying to integrate the audiotracks package but I'm getting NoReverseMatch error. The documentation states..

Add audiotracks to your app ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Edit settings.py and add audiotracks to your list of INSTALLED_APPS. Then synchronize your database with::

$ python manage.py syncdb

Edit your ROOT_URLCONF_ and add a piece of code similar to::

urlpatterns += patterns('',
    # Here we mount the app under /music. Feel free to use something else
    url("^music", include("audiotracks.urls")),
    # Some URLs require a Django username
    url("^(?P<username>[\w\._-]+)/music", include("audiotracks.urls")),
)

Visit the URL /music/upload to upload your first track.

the error occurs when i try to access music/upload..

here's the full traceback.

You cannot have followed that instruction; apart from anything else, patterns no longer exists in Django 1.11. Please show your full urls.py. — Daniel Roseman

from django.conf.urls import url, include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from django.views.static import serve
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^account/', include('account.urls')),
    url(r'^music/', include('music.urls')),
    url(r'^music/', include('audiotracks.urls')),
    url(r'^(?P<username>[\w\._-]+)/music', include('audiotracks.urls')),
]

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

if settings.DEBUG:
    urlpatterns += [
        url(r'^site_media/(?P<path>.*)$', serve, {
            'document_root': settings.MEDIA_ROOT
        })
    ]
    urlpatterns += staticfiles_urlpatterns()
