Should I change myself for someone I love (not reciprocated)?

I went ice skating with these two girls about a week ago and we are all really close like sisters. When we were in the car we were talking about the music we like and I felt really left out as I don't like any music that they like, they like N-Dubz, Jenifier Lopez, Pitbull and Ne-yo. Whereas I like Frank Sinatra, Dean Martin and The Beatles and when I said I felt left out (I meant it as a joke) my absolute best friend said "well you will have to like something modern at some point you can't stay stuck in the 50's fovever". This would not normally have bothered me but I love this girl and I don't mean as just friends (I am a closet bisexual) I love her so much and it has made me want to change myself for her and I haven't stopped thinking about it. Should I change myself so she will like me a little bit more? I feel so pathetic now.
ADDED SECTION ---------> I have always been proud of who I am and I never would want to change for anyone but this girl makes me want to change everything about me if it would make her happy.

If you have to go through life adjusting yourself to fit your friends likes and dislikes, you'll be miserable. You and your friends just need to appreciate your differences. Diversity is a good thing.

As Popeye put it, "I yam who I yam." :-)

I second what Rob said. It's better to be loved for who you are than for who you pretend to be. If you ever want to make a change in your life, change for YOU, not someone else.

I agree with rob. Your friends must like you for who you are because they hang out with you. Don't change yourself. Just be you.
