Hi, female MusicBee user here! I've been using MusicBee for a long time now, but decided to create a forum account today.
I like to be as organized as possible, so MB is perfect for me, even though I don't have a particularly large library. I spent about a week tinkering with it until I achieved something I'm satisfied with, and I absolutely love it! I use MB for audiobooks and music, so I really appreciate having custom tags that keep my audiobooks organized the way I want.
As to whether or not music collecting is male oriented, I haven't really seen that myself, but it largely depends on the people you're surrounded by, doesn't it? Personally, I just like being organized and can't tolerate having untagged music, and I know quite a few people, both men and women, who feel the same way.
