I think the thing that lesbians have in common is that they are women who are attracted to women, so I don't think any statement can be made about what kind of music lesbians might like as a group. Would be like asking what kind of music do women or people who love women (ex, straight men) like. So I am thinking lesbians enjoy all kinds of music.
I made a page that looks at the music of women who are either openly gay or who have been associated with loving other women. Maybe you will enjoy the music they create... I do!
