Any screamo, metal, or people who can't sing go in this category as well.

Ok, I'm sorry, but I really don't get why people DON'T like screaming in music. It's so expressive, especially when blended with really astounding vocals and even better when it's like really pop - style vocals and then theres a wdk breakdown...but thats not the point...You can express massive outbursts of emotion, as if something was just tearing to get out, express times of pain and suffering, express great energy (my personal favourite), get a pounding rythem going. As I said, also really great for breakdowns.
And before you call me a metal head, I do love singing as well, (Nightwish, Incubus, Daft Punk, Gackt, Evanescence, Muse, Coldplay and many others). There are just so many types of music for different times that its insane (insane I tell ye) to say that singing is better than screaming because that disqualifies so many different genres of music. Plus there are different types of screaming (it is true). You listen to Atreyu and Emery, or Still Remains and Mad Capsules Markets (RIP 1990 - 2006) and you'll hear that they are expressing themselves differently through different pitches, tones and sounds...
...'gasp'...ok I beaten 'flips on some Funeral For A Friend'
...Oh yeah, and best is - Mad Capsule Markets/Luna Sea (I know they are completely opposite in style but I believe that the greatest band in the world would be a mix of the two that blended the styles perfectly)
Worst - Just overplayed stuff really - Anything off American Idiot...and overplayed Queen stuff. Though most bands recieve their respectability back when everybody lays them to rest (finally) e.g Linkin Park, Evanescence (Im sure I've had most of this conversation in the overplayed songs thread :S)
