Gee, maybe I can become a Spotify Power User, now that I'm doing my homework:

You can refine your searches in Spotify by adding extra terms into the search box. Note: search terms are not case sensitive.

Search by artist

artist:Radiohead – lists all tracks by Radiohead
Search by track

track:"My Sound" – lists tracks with the name My Sound
Search by album

album:Loveless – lists the album Loveless
album:"Many Faces Out Of Focus" – use quotes when the keyword contains spaces
Search by year

year:1969
year:1989-2013
year:1989-2013 NOT year:1993
Refine your search with AND, OR, and NOT.

Kyuss AND Green – lists results with keywords 'Kyuss' and 'Green'
Zeppelin OR Floyd -- lists results with keywords 'Zeppelin' or 'Floyd'
Metallica NOT Anger – lists all Metallica tracks except with the word 'Anger'
Instead of using AND or NOT you can also use a plus sign (+) or a minus sign (-).

Further search options

genre: Displays music in the genre matching keyword. See the list of all genres, for example genre:blues, genre:"rock and roll".
label: Displays music released by the label matching keyword.
isrc: Displays tracks matching ID number according to the International Standard Recording Code.

tag:new - Lists the most recently added albums. 'Tag' won't return results for any other keywords.
