Music taste, like anything else, is something two people can have in common. Naturally, the more you have in common, the more you connect with that person, at least on that particular level.
Most of my friends have a similar taste to mine. The differences are what I look forward to - expanding my taste as I am introduced to artists/genres/etc I otherwise would not have known about.
That being said, I once discontinued a relationship with someone for playing Britney Spears in my truck.
