The similarities between songs are quite literal (e.g. songs are similar in some technical sense), but their mood, cultural meaning, etc., is completely different. I got some pretty festive pop as recommendations for similar songs to Enjoy the Silence from Depeche Mode - but the chord progressions and amount of syllables in choirs were similar. No idea how this works and whether that's by chance or on purpose.
