On my NAS (Buffalo LinkStation) I’m using mt-daapd in order to show playlists on iTunes …
Automatically create smart playlists?
I have arranged .mp3 using paths on filesystem :
- preferred : is the directory for my favorites music
- matrimonio : directory of my wedding music
- stefania : directory for my wife’s music
- <artist> : directory for artists
I used Jaikoz (auto tag) in order to arrange my music
Playlist for mt-daapd can be created editing file mt-daapd.playlist.
Format is :
"<name_of_playlist>" { <filter criteria> }
You can read all details about syntax into mt-daapd.playlist (here there is a description of format).
For example:
"90's Music" { Year >= 1990 && Year < 2000 } "New Music > 2000" { Year >= 2000 } "PREFERITI" { path includes "00_PREFERITI" } "Recently Added" { Date after 2 weeks ago }
Below a one-single-line shell command in order to create playlist starting from filesystem structure.
STEP #1
Backup current playlist:
cp /opt/etc/mt-daapd/mt-daapd.playlist /opt/etc/mt-daapd/mt-daapd.playlistcpy2010-05-01
STEP #2
find /mnt/disk1/share/0_MP3/ -type d -maxdepth 1 -exec basename {} \; | awk '{ print "\""$0"\" { path includes \""$0"\" } ";}' >> /opt/etc/mt-daapd/mt-daapd.playlist
STEP #3
Restart mt-daapd and use iTunes in order to check the final result.
Syntax
# The syntax is as follows: # # "Playlist Name" { expression } # # An expression consists of: # # ID3-tag-name operator operand # # Where valid ID3-tag-names are: # Artist (string) # Album (string) # Genre (string) # Path (string) -- full path to song, including filename # Composer (string) # Orchestra (string) # Conductor (string) # Grouping (string) -- I don't even know what this is... # Comment (string) # Type (string) -- "mp3 audio file", "m4a audio file", etc. # Year (int) # BPM (int) # Bitrate (int) # Date (date) # # Valid operators include: # is, includes (string) # >, <, <=, >=, = (int) # after, before (date) # # the "is" operator must exactly match the tag, # while the "includes" operator matches a substring. # Both matches are case-insensitive # # Valid operands include: # "string value" (string) # integer (int) # # Multiple expressions can be anded or ored together, # using the keywords OR and AND (or || and &&). # The unary not operator is also supported using the # keyword NOT (or !) # # Examples: # # "techno" { # genre includes "techno" || # artist includes "zombie" # } # # This would match songs by "Rob Zombie" or "White Zombie", # as well as those with a genre of "Techno-Industrial" or # "Trance/Techno", for example. # # "AAC Files" { # path includes ".m4a" || # path includes ".m4p" # } # # This would match all m4a and m4p files -- i.e. iTunes-ripped aac files # or songs downloaded from iTMS. # # "Orchestral Music" { # Orchestra !IS "" || # Conductor !IS "" # } # # This would match anything with *anything* entered as a # orchestra or conductor... this would probably include any # orchestral music. Kind of ugly, but works! # # # DATES # # Dates are kind of funky. The "date" of a file is when it # was created on the file system, or the date that it was first # entered into the database, whichever is earlier. The date of # a file can be matched with the terms "before" or "after". # # One example of a valid date is a date in yyyy-mm-dd format: # # "Files added after January 1, 2004" { # date after 2004-01-01 # } # # There are also some special date keywords: # "today", "yesterday", "last week", "last month", "last year" # # A valid date can also be made by appling an interval to a # date. As an example, a valid date might be: # # 3 weeks before today # or # 3 weeks ago # # You can combine these, of course. # # "3 weeks before today" is the same as "2 weeks before last week" # or "1 week after last month" or "21 days before today" or # "20 days before yesterday" or "7 days after last month". You get # the idea. # # Note that the playlists are only generated at the time that mt-daapd # starts... so while the dates will be accurate at start time, they # may become inaccurate with time. Yes, I know... it's on my list. :) # # So, examples: # # "Recently Added MP3s" { # date after last month AND file includes ".mp3" # } # # This matches only mp3 files added in the last 30 days. # #
