Much harder because we need id3 parsing for everything:

/music/artists                [artist1, artist2, artist3]

/music/artists/artist1/album1 [song1/_meta/media, song2/_meta/media]
/_meta/image/music/artists/artist1/album1 - album art
/_meta/media/music/artists/artist1/album1/song1 - direct link to song, served by webserver

/music/songs                  [.../artist1/album1/song1/_meta/media, etc]


Config file

these are defaults, if not present in the config file
provide rest api for configuring
provide web UI which uses JS to talk to the rest ui
look up config stuff every time you do anything; cache nothing
tv = "$XDG_VIDEOS_DIR/tv"
movies = "$XDG_VIDEOS_DIR/movies"
music = "$XDG_MUSIC_DIR"
placeholder_image

_meta
when requesting anything from _meta other than media, look for the appropriate
file. If it does not exist, put a placeholder in its place and serve the
placeholder. All _meta information is stored in XDG_CACHE_DIR.

indexer
look for placeholders and replace them with the real thing
