This probably warrants its own thread on the cactus cafe thread, but I'm not sure anyone goes there anymore
This thread has turned into a Seinfeld episode. Hell, NJ is talking about his preferred remedy for his cycling-induced butt rash. I don't think anybody is going to complain that you're making an off-topic comment that would be more appropriate in another forum.
I actually think he has a good voice in a non-traditional way (when he's not doing the yell-growl thing - here's an example). I tend to judge vocals by whether someone can sing on pitch, and he actually can. He has a gravelly rough voice which frankly isn't getting any better with age, but there's something to be said for someone who can sing on key even if their vocal style isn't standard. I used to hate Bob Dylan's voice with a passion but it sort of grew on me over time. And there are some other artists like that as well.
He probably can sing on pitch, but he frequently doesn't. Furthermore, I don't like the gravelly sound, which I think is somewhat part of his rap. Frankly, I just don't like that style of singing - ditto for Bob Dylan.
I was always fascinated by how four guys like Don Henley, Glen Fry, Joe Walsh and Timothy Schmidt could all have such vastly different vocal styles, and none of them are what I'd call traditionally great singers except for Tim, but their harmony was still just amazing.
I'll always be impressed with singers who can truly harmonize, and those who can sound great even if their voices aren't ideal. The Eagles are an excellent example of that.
