It was explained to me once by a very respected musician that the vocalist is very much like another instrument. They should complement the song. Consequently, I'm not really interested in their range, etc. (heck, my voice has a several octave range if I'm annoyed, lol) If their goal is to take over the music it doesn't count with me. The vocal gymnastics exhibited by many, for instance.
Just as a side note...not really relevant at all...I am more likely to listen to male vocalists with deep voices. Johnny Cash, Waylon, Toby Keith, Tennessee Ernie Ford. Same with female. Patsy Cline, Cassandra Williams, MaMa Cass.
Although I usually listen to classic rock...I generally find the octave range that appeals to me in older C&W, jazz.
Disclaimer: I didn't read the list. Rolling Stone, well ya know.
