Tracks played via playlists missing from stats

[Nic83]

Hello

So I'm trying to test out how the songs I listen to come out in my "listening stats". There's a few playlists that I frequently listen to a lot, to the point I hardly listen to anything else of my own selection and yet the songs that these lists are made of are nowhere to be seen in my most played songs. They don't even appear on third party lists such as from Stats by Spotify for instance. Anyone got any clue why this could be?

Thanks
