The music or the misery

High Fidelity is one of my favourite books ever, in fact it's probably the book I've read more then any other. I even have the pages with my favourite bits on them folded at the corners.
Obviously it's a favourite because its about music and people who love music and who let it have a huge role in their life's.
But my favourite parts in the book are the parts where the main character talks about which came first the music or the misery, and every time I read it it makes me think.

" Maybe we all live life at too high a pitch, those of of us who absorb emotional things all day, and as a consequence we can never feel merely content: we have to be unhappy, or ecstatically, head-over-heels happy, and those states are difficult to achieve within a stable, solid relationship."

What if this is true? Does that mean I have to give up listening to music and reading books and watching films in order to have a healthy attitude to love?
Do I have unrealistic ideas about what love is because of the songs I listen to?
Or I am just endlessly hopeful that the feelings expressed in these songs can be real, because they must be because someone felt them and made a song out of them.

I don't wanna give up the music but I also don't want to give up on the idea that I can find the kind of love that has inspired those songs.

Maybe it truly is unrealistic, I hope its not but really I have no idea.
