You will absolutely need to know whether or not you've netted yourself an incompatible partner however much there's an 'amazing' chemistry between the two of you.
You'll have been traumatised before and you'll want to prevent it happening again if you can.
I have yet to meet a couple who models relationship happiness who have opposing interests in music. Check out profiles and listen to the music of your matches.
Your question is then: "Can we make it together and survive troubled times?
You could get a 4-note match (high likelihood) with someone who likes different music than you. I noticed dramatic differences in personality between people who were passionate about music versus people who were in the music business just for the glamour of it, and who did not listen to music in their free time.
Of course, the music we like to listen to is important. Visitors of your page can play the music for free and vice versa. You are likely to discover new music you will love. They experience the world in a similar way as you, and so you have a better chance of getting along. The day after an awful date (with a man who listened only to 80's hair bands), I was convinced that music could predict compatibility and I set out to prove my theory.
However, you can't allow yourself to rely on anything other than any personal responsibility for your future happiness.
