Refresh Smart Playlists Using AppleScript
|
 |
| |
Let's say that you have a bunch of smart playlists that choose a certain number of random songs of a given genre (or grouping) from your iTunes library. Let's also say that these are synched with your iPod, and thus you would like to automatically refresh those smart playlists, say, once a week so you always have fresh music on yer 'pod. Just set this AS to run once a week using, for example, `crontab` in Terminal:
set playlist_list to {"names", "of", "smart", "playlists", "to", "refresh"}
tell application "iTunes"
repeat with the_playlist in playlist_list
delete (tracks in (first playlist whose name is the_playlist))
end repeat
end tell

Smart playlists that truly follow your mood
|
|
| |
With thousands of tunes in your iTunes library or in your iPod, it's high time to consider using it as the radio you've always looked for: the one that delivers only tunes you like, and that fit your mood in a unheard of way. The idea is to extend objective parameters provided by iTunes, like last played time, genre, etc. with subjective parameters like warmth, violence, restfulness, modernity, whatever you want. Then, you build smart playlists upon these parameters, regardless (or not) of genre. iTunes will mix your songs in sometimes unusual ways, but always relevant, and sometimes quite stylish!
For example, a "Soft" playlist contains all tunes that are both warm and restful; the "Well Awake" playlist contains tunes which are not restful, and not too violent; "Pop" playlist contains tunes which are popular but not too much main-stream; "Pop++" contains only (assumed) mainstream popular tunes, etc. I'm happy with a system of tagging which works quite well after months of usage.
For each dimension, I give a note to each tune, within "irrelevant," "not at all," "yes," and "yeah, definitely." Those four steps seems to be enough. And more steps would make smart play list hard to design. For example, let's take violence. I add in the comment (the grouping field may be preferred) of each tune "Violence-," "Violence=," or "Violence+," depending on its violence. Violence- means calm, Violence= means violent, and Violence+ means ultra violent (God knowns that some songs are). If a song is not tagged Violence, it is considered not violent, and not calm, let's say, normal. Here are examples, on a few tunes that many of you may know:
Miles Davis - Flamenco Sketches : Modern=, Pop=, Rest=, Violence-, Warm+
Louis Prima - Just A Gigilo / I Ain't Got Nobody : Modern-, Pop+, Warm=
JS Bach - Goldberg Variations : Modern-, Pop=, Rest+, Violence-, Warm+
The Beatles - Sgt Peppers - A day in the life : Modern=, Pop=, Trip=
Deep Purple - Speed Kind : Modern=, Pop=, Violence=
Massive Attack - Protection : Warm-, Modern=, Pop+, Trip=
Einsturzende Neubauten - Negative Nein : Modern=, Pop-, Rest-, Trip=, Violence+, Warm-
With two conditions maximum, you are able to precisely target your tunes:
Something violent but not too much? Comment contains "Violence=".
Something violent, even very violent? Comment contains "Violence" but not "Violence-".
Something which is not violent? Comment doesn't contain "Violence=" nor "Violence+".
Something which is not violent and not calm? Comment doesn't contain "Violence".
Now here are a few of my smart playlists :
Melancolic: any genre, tune is Warm-, not Violence+, not Violence=, not Rest-
Good mood: any genre, tune is Warm+, not Rest+, not Violence+, not Pop-
Soft: any genre, Warm but not Warm-, Rest but not Rest-
Pop: genre is not jazz, not classical, tune is Pop, but not Pop-, Modern but not Modern-, not Trip+, not Rest, not Violence-, not Warm-.
Junkie: genre is not classical, tune is Trip but not Trip-, not Violence+, not Rest-
Not archived on CD: tune is Archive-
This may look over-complicated - and it is a little. When Apple gives us the ability to really play with the iTunes database, things will change. I also admit that I spent a long time tagging tunes. Some albums are easy to tag, but those which contain very different songs require more time to be well tagged.
Anyway, now my iPod is my favourite companion within the non-humans -- it never fails giving me what I want to hear. This is completely new to me -- like, er, I live in the XXI century?
