Show HN: I built a site that lets users find playlists by songs they contain
I once built a site that used Spotify playlist data directly. The intention was that you could take one of your own playlist and find playlists that have the greatest overlaps. The intention was to find people with a similiar musical taste to yourself.<p>Interestingly I found a lot of new music that way and also found other music directions that suddenly interested me.<p>Thinking this a little further, it provides the perfekt basis for a dating application. Music is a very personally representation of oneself and if you find someone who has the same muscial taste, you already have a common basis for communication.<p>Obviously this never made it past developer status since Spotify does not like third party apps storing their data (i.e. playlists of other people). You can use the data but not store it or analyse it.<p>It made me think that Spotify should build a dating app since they would have no interest in keeping you in their dating app as thats not their main business, unlike other dating platforms that have little interest in losing their customers.
