Reverse lookup: every movie/show/ad a song appears in
Problem
Music identification apps tell you what song is playing, but there is no service that, given a song, shows you every piece of media it appears in - movies, series, trailers, commercials, games. People trying to trace where they know a track from have to dig through fan wikis and forums.
Opportunity
A 'where have I heard this song?' database that aggregates soundtrack listings, sync-licensing records and community contributions into one searchable song-to-appearance index, with audio-preview matching for covers and remixes.
Market analysis
Tunefind already does the core job with a large community-maintained database covering movies, TV and games, and WhatSong covers a similar space; the song-to-media index exists and is actively updated. The genuinely unclaimed slices are ads/commercials and deep audio-matching for covers and remixes, but data acquisition there is expensive and licensing is treacherous.
Market · Curious music fans and 'where do I know this from' searchers; broad but low-intent audience, with music supervisors and sync researchers as a small high-value niche.
Pricing · Tunefind runs a subscription for power users (historically around $5/mo); ad-supported free tiers are the norm; willingness to pay for casual lookups is very low.
Pros
- + Clear, evergreen user need with proven search volume around soundtrack identification.
- + Ads/commercials and cover/remix matching are genuinely under-served by Tunefind and WhatSong.
- + Community-contribution model gives a plausible bootstrap path for the long tail.
Cons
- − Tunefind is entrenched, community-fed, and effectively free for the common case.
- − Aggregating sync-licensing records is hard: the data is fragmented, proprietary, and often not public.
- − Audio previews require licensing deals with rights holders; covering commercial use adds another layer.
- − Monetizing casual 'where have I heard this' traffic is notoriously weak.

The wedge that incumbents structurally ignore is advertising sync: Tunefind’s community model works when fans watch a show frame by frame, but nobody catalogs the thousands of regional ad placements a catalog track accumulates, which is exactly the “where do I know this from” itch that TV-focused databases miss. That data has a second buyer, music supervisors and sync agencies who currently track ad placements manually, so a B2B2C angle could fund the consumer-facing free index. Without that wedge this is a Tunefind clone with a decade of community moat to overcome.
