usage_description="
|
|
Finds the original release year of a given track or album via a search query of the top 10 results and taking the oldest release date
|
|
|
|
Especially useful to find the original dates of songs that get re-released in 'Greatest Hits' type albums
|
|
(eg. use in script to find songs from X decade regardless of which copy of the songs are in your playlist)
|
|
|
|
The search must be as specific as possible for accurate results and should include both the artist name as well as the track/album,
|
|
preferably with the artist specified as artist:<name> eg.
|
|
|
|
<track_name> artist:<artist_name>
|
|
|
|
<album_name> artist:<artist_name>
|
|
|
|
Examples:
|
|
|
|
Tracks:
|
|
|
|
${0##*/} sweet harmony artist:the beloved
|
|
|
|
${0##*/} artist:the beloved track:sweet harmony
|
|
|
|
${0##*/} kylie on a night like this
|
|
|
|
Albums:
|
|
|
|
SPOTIFY_SEARCH_TYPE=album ${0##*/} happiness artist:the beloved
|
|
|
|
SPOTIFY_SEARCH_TYPE=album ${0##*/} artist:the beloved album:happiness
|
|
|
|
For more details on search query syntax see spotify_search_json.sh
|
|
|
|
|
|
Caveat: this is only as accurate as Spotify's data which is usually fairly good, but if Spotify has only managed to license a song via a later compilation album then we can only report the earliest release date which may not be the real original release for a classic. An example of this is
|
|
|
|
artist:\"Carl Douglas\" track:\"Kung Fu Fighting\"
|
|
|
|
Which I know is a 70s song but Spotify only has it on compilations dated 2001 onwards, leading to an incorrect result in that rare case.
|
|
|
|
In a rare case you may need to tune the number of results from which the original date is inferred to more than 10 using the SPOTIFY_SEARCH_LIMIT environment variable but in my testing the first 10 results have always contained the original version from which to infer the oldest date,
