it should be put into categories, such as female grunge, female punk, etc. i love female grunge, but this tag is useless it includes all female musicians NOT COOL divide it into something more specific!
there is actually nothing inherently superior about an ugly guy who can sing as compared to a pretty girl who can't. we just value voice over looks. the "where's the male vocalists" stuff kind of reminds me of people who are like, "omg why do girls get a women's officer? there should be a men's officer omg!" i like this tag because i actually prefer to listen to a lot of music sung by girls rather than guys. and because socially speaking, the female lead vocal tends to seem to have an *otherness* about it, like the male lead vocal is the default. oh i wonder what helene cixous would have to say about THIS...
and why there is a tag called famale vocalist.. and another called female vocalistS???
i dont se a difference if the are used for solo artists... i would understand it if for example it was used for groups who 2 or more women sing otherwise its just confusing
There is no genre limit on this tag. It does make it a lot easier to sort through metal and alternative bands with this tag however.
A "male vocalist" tag would be plain idiocy. Assuming all female fronted bands are being tagged with "female vocalist" one would think all bands/artists not tagged with this have male vocalists.
Pop and Symphonic Metal are probably the only genres off the top of my head where you might see more female vocals than male.
It IS a useful tag, regardless of what any narrow-minded person may think, otherwise it wouldn't be here.
They mostly suck. and :
stupid tag....... because nobody uses tag Male Vocalists 
Like there isnt too many female singers already. Every woman that looks good can become a "singer" talent isnt required
