One thing you may want to keep in mind about Los Angeles: the place is crawling with young, drop-dead gorgeous women -- model and actress hopefuls, the women who were the most beautiful girls from their town and are now just little fish in a big pond. The men you are interested in -- musicians and rockstars -- have their pick of the youngest and most beautiful of these girls.
Which is not to say you can't find a great man here. But if you are a 35 year old woman who is less than stunning, and extremely picky as you have admitted, it doesn't matter how much you know about or love music. Why do you think men become musicians in the first place?
