Yeah but thats ineptitude. I don't think its a lot to ask why you like something. Saying their better is not a valid position when one asks "why."
Yeah I think Seltzer and Boo Boo are talking about different things.
With regard to Seltzer, I got these he's taking aim at these "soulful" singers who are just well packaged mall-crowd sheen. Anytime a candidate on American Idol uses a melisma (sp?) or dips down to their gospel depths, I find it contrived. Its for people who havn't heard passionate music to say that its passionate.
With Boo boo, I don't think he likes the use at all. Springsteen looks like he's having a heartattack on stage everytime he plays, he works his craft over and over. I don't think its out of line to say he's got more passion than a Pete Yorn or something. And I cetainly think its a reason that he's better.
Passion tenRAB to lead to better overall products, just because I cite it in a song isn't wrong though. When the White Stripes opened for the Stones, Jack White said they were still arguing over how to play "Satisfaction." Their not just going through the motions as a lot of detracters would suggest looking at their ticket prices.
