Upcoming is not a trophy case
If you save every on-sale as a gig you “attended”, Wrapped will lie. Upcoming in Radar is for dates you are actually targeting.
When the night happens, it flips to past. That is the only promotion a wishlist item should get.
A short list stays useful
Five upcoming shows is a plan. Fifty is a feed. Delete the ones you have already missed.
Use Find to add from real listings so artist, venue, and date are correct — then buy tickets from the official link.
Past is the product
Friends, ratings, photos, and setlists live on past gigs. That is the diary people mean when they search concert tracker.
Keep the wishlist thin so the history stays thick.
