The thing about vocals for me is that they can't just sound pretty, they need to hold my attention for a whole album. I can easily listen to most male vocals (except the vocalists from Megadeth, Avenged Sevenfold, Volbeat and a few others: they can all go to voice box hell as far as I'm concerned) but with females my taste is a lot more restricted for some reason. I don't know why I just get bored with a lot of female vocalists after a few songs. Delian, newer Nightwish, Lacuna Coil, Halestorm, etc, are fine for a song or two, it all just gets boring rather quickly though. Strange.
