I first had this question back in 2020: what if you could double-click into any song and see its entire lineage? Like what songs sampled it, what songs it sampled, what it inspired, etc.
Finally, 6 years, I started exploring it and trying to build it. But before getting too far, I found out found out that Spotify had literally just shipped this (“SongDNA”).
So I’m not building it. But I feel validated by it. The fact that a billion-dollar company spent real money on the same question tells me that the instinct was right.
