So how does this work for vocals?

[Indigo_Dingo]

How will female vocalists do songs with males singers, and vice versa? Do they have male and female versions? Do they record a male and female version of each? Cause that would get weird, a guy singing "Magic Man"?

For vocals, some songs I'd like, and think I could do well, are:
The Red and The Black - Blue Oyster Cult
Set It Off - Audioslave
Flight of the Icarus (if you can pause it halfway into "Fly") - Iron Maiden
The Thin Line Between Love and Hate - Iron Maiden
Journeyman - Iron Maiden (you can see where I'm going with this)
All Along the Watchtower - Jimi Hendrix
Piece By Piece - Slayer
My Michelle - Guns n Roses
Beheaded (upper vocals)- Demon Hunter
Dani California - Red Hot Chili Peppers
Blood Red Skies - Judas Priest
Rent - Rent (There are guitar and drums in it)
Blood of Heroes - Megadeth

But how do you order it? Difficulty for vocals cannot really be quantified.

It wont really matter on your sex, you just need to be able to make your voice go higher and lower when appropriate, and also pronounce the words, of course.

indigo, of course it would sound wrong to a normal audience for a girl to sing a demon hunter song or something of the like. but for this game all you have to do is be on key.

Well, once on an episode of the osbournes, there was a girl, who has won a prize to stay for a couple of days at the osbournes. She sings in a band, and she can go really, really low with her voice. She's growling like an animal!!! It really sounded as if only a man could do it! So with some practice, females can do the same things as men with vocals.
