Similar Wave-Lengths

I have this interesting connection musically to a good friend of mine.  It is scary how similar our tastes our.  I mean, it seems like any band that I thought only about 10 people know about, she knows as well.  She first noticed this when she had a pandora station up, and I kept singing along to all the songs that came up.  This has been staying true for awhile now, and its just crazy how similar our tastes our.  Our brains are wired up to appreciate the same type and styles of music.  We also have some similar personalities traits.  You ever find someone that you seem to be in tune with?  I had a good friend in high-school that also had my same attitude and more or less likes that I did.  Some people I can just click with on a greater than normal level.  Not just friends, more close than that (not a relationship like that, but just a closer than normal feeling/bonding).
