Database schema:

CREATE TABLE tags (
	"index" INTEGER -- example: ['0', '1'],

	tag TEXT -- example: ['funk', '1970s'],
	PRIMARY KEY ("index"), 
	CONSTRAINT fk_tags_torrents FOREIGN KEY(id) REFERENCES torrents (id)

CREATE TABLE torrents (

Question: What is the release title of the single under the "funk" tag that was released the oldest?
Evidence: release title of single refers to groupName where releaseType = 'single'; the oldest means coming before all others in time and refers to MIN(groupYear);

SQL:
SELECT T1.groupName FROM torrents AS T1 INNER JOIN tags AS T2 ON T1.id = T2.id WHERE T2.tag LIKE 'funk' AND T1.releaseType = 'single' ORDER BY T1.groupYear LIMIT 1
