Hmm this seems very niche and gimmicky. Sure, it's good if your partner doesn't listen to music that makes you want to stab your ears with knitting needles, but there's so much more to compatibility than just music. To some extent, I'm wary of quantifying things that make up a good match. That's why I started looking into Richard Easton's matchmaking service because it's nice to have that personalized touch. I like that traditional approach to matchmaking, the personal recommendation of one person to another rather than some machine crunching numbers or some special generalized equation. But to each his own, I say. Do what works for you.
