It really depends on how big her tits are...
(ow! stop hitting me!)
Seriously, by your rationale everyone should expand their taste in music so they can appreciate different people .... hmm. Doesn't sound half bad.
Please don't judge someone by their musical tastes. That's like judging someone's social competence by the amount of time they spend on internet forums...
I dated this beautiful woman - flight attendant, ex-lingerie model and really funny and fun to be with. Turns out she was into country music (I didn't have a clue) - I was so into her, and she loved teaching me all about it during the 4 years we dated. The point is, that different musical tastes can be a good thing if you have an open mind. She's now my ex-GF, but we're still good friends -
The music will always remain with me to remind me of some really great times we had.... (*sniff* Where did I put that frigging iPod?)
