Songs not sung in Harsh vocals?

I was actually already into both clean and harsh vocals before I got into Opeth. \(o_O)/

I don't really see the problem with HD only liking those types of vocals. They certainly take talent and can sound much more interesting than a usual voice on occasion.
 
Funny how Opeth unite people with various musical backgrounds, if we all name 10 other favorite bands, it's gonna be a really crazy list...
