Mad girlfriend

So I have this problem, I've been dating this girl for 4 months and I am a big fan of music and i like to mix myself in fruityloops some music, the first month i liked to show her my music and I was really enthused about it, she however was not and did not like it much, and i really havent bothered with it much since but now i just spent 4 hours making a song with my best friend and I was happy with the result, i got home to her later in the evening and I really felt like showing her the song, now recently shes been getting mad at me a lot and this time she said she was as interested in my music as i was if she was to show me her nail polish collection.. She said also that i was like a 6 year old kid showing my mother a ugly drawing i just did and it bothered her... Now what should my reaction be? Should i have known she wasnt interested and kept it for myself? Or a. I right for being mad about this

dear 1st worldprobs, why are you soo much keen on showing her everythnig u plan to do? every individual is different from other, none of the peoploe on the planet are the same, dont keep on showing her what u did into music or what not, just continue your passion for music, and some day she will listen t it and maybe even appreciate you for your work, meanwile to make her interested in your music compose for her or sing for her, maybe she will see your efforts an start liking music, ignore it what ever she said, dont take it too seriously, otherwise it will mess up your brain. wish u luck with your music. tc.

Okay I think that it's good you show her your music, I think you should share interests but she obviously doesn't like it then show her something less frequently once a month or something. The thing she said about it being like an ugly drawing, out of line in my opinion. You shouldn't compared your boyfriends passion to an ugly drawing it's just ridiculous. I'd be mad.

I appreciate all replies, To answer the latest reply, I haven't shown her anything of my stuff for 3 months because she's told me she doesnt like it, However I was just really enthused about it and wanted to share. To Susiedqqq, I believe it's in no form of jealousy that she got mad, I've spent most of my time with her for the last weeks, I was meeting up with my friend for the 3rd time since december or so, And my routine is Work - Gym - GF time - Sleep - Repeat.. Buy her dinner and romance her? In the last months I've paid for most of her food, and I even made her an easter egg made of chocolate for easters...
