Dennis Miller joked about it in a comedy special: "yeah, I know for a fact that Axl Rose can still belt out the tunes...I hear him every day when he's cleaning my neighbor's pool." Lol.
But - like many of us - one my favorite things about music in general is its' ability to evoke feelings. And that can take SO many forms
Bottom line: if it stirs your feelings, makes your butt move, or touches your heart, that's good singing to you. Very well put shredd.
I have two examples of singers that I like that a lot of people (including my wife) can't stand.
Billy Corgan. Yes, he of the whiny voice. Yet, he has a lot of listeners just based on the Smashing Pumpkins album sale alone. Dude can write and create (or at least the earlier stuff). Also a very good and underrated guitarist. I know SP isn't for some people just based on his voice alone. The album Melancholy & the Infinite sadness is a rollercoaster of emotions. As a side note their drummer Jimmy Chamberlain is outstanding.
I would say that BC is not much different than a Bob Dylan, Neil Young or Tom Petty for the same reasons people like these artists. I like Neil Young, don't listen to Bob Dylan, and I personally think Tom Petty is boring and overrated. However, a lot of people would disagree with me on that (including my bother and his wife) but it always boils down to what you stated above.
The second guy is Harvey Danger's singer Sean Nelson. I know what you're thinking ... Harvey who? The one-hit wonder band of the late 90's song Flag Pole Sitta
It's easy to write them off as a one-hit wonder and him as another whiny singer that's not that good. I would say the same at first glance, but for me digging deeper led to, to my ears anyway, a very good "conversatioinalist" style writer and a solid band. I would even gesture some Beatles influence comes through. His voice is whiny in parts, but also very good in others. Maybe similar to Neil Young's in that way.
This is their hit song
An example of a bit whiny in parts mixed with a strong voice in others
I hear Beatles influence on this one
