# User pages
# /:login - all non-empty playlists
# /:login/music - all non-empty playlists with at least one audio (shows 10 audios per playlist max)
# /:login/video - all non-empty playlists with at least one video (shows 10 videos per playlist max)
# /:login/pages - a list of user pages
# /:login/:page_name - a single user page
# /:login/blog - a list of blog posts
# /:login/blog/:id/:slug - a single blog post

# If default playlist is empty, it redirects to the user's page
# Pages and blog posts can contain: audios, videos, youtube videos

# Tracks and remixes can be paid. See /shop page
