There needs to be an app that scans 2 (or more) people's music libraries and creates a play list of songs you both love.

· Shower Thoughts Link · 1 · 1 · 2


$ for i in 0 1 ; do sort playlist$i | uniq ; done | sort -R | uniq -d > playlist

or, even better

$ ls playlist{0,1} | parallel "sort {} | uniq" | sort -R | uniq -d > playlist

The number of playlists may be more than two, but the result will then include every song at least two persons like.
