You could certainly ask for stronger consensus (or file an RFC, which I (personally) don't think is quite needed at this stage), Moscow, but to use arguments that those were there from the start and your opinion (and opinions of others who apparently haven't chimed in here) are more important because you wrote it and take care of it more is displaying bits of WP:OWN behavior. Can you show us an abundance of reliable secondary sources that specifically use the "scream, dance", etc. bits? Officiality doesn't make a source more reliable by Wikipedia's standards or more important. Piper's Picks says Piper Reese is the "Princess of the Press", but the Wikipedia article doesn't make mention of that title because it's not widely used in reliable sources. I personally believe it's okay to make mention of the types of vocals in a section discussing musical style or something of that type, in prose and backed up by reliable sources. I just think that in a list "vocals" or "vocalist" is best. (And to SilentDan, I'm sorry I haven't chimed in to the question you asked. I've been busy the past few days and I haven't had the time to really think about it. I don't have time right now, either (I've already typed too long and must be off to something else), but I promise to add my thoughts about the other later.) -
