Which data to extract. The category must match your 'mode'. 'get' supports all entity categories. 'search' supports search_* categories. 'chart' supports chart_* categories.
⚠️ Concert categories — pick the right one:
• 'search_concert_locations' = look up CITIES/PLACES (queries are place names like 'London', 'Buenos Aires'). Returns geoHash/geonameId.
• 'search_concert_artists' = look up upcoming concerts BY ARTIST NAME (queries are artist names like 'The Fratellis', 'Flook'). Returns concert/tour dates.
• 'artist_concerts' = same as above but you already have the Spotify artist ID/URL.
• 'concerts_by_location' = list every concert at a specific geonameId.
