I do notice a difference of voices of Pop and alt rock like the article says, versus Classic Rock, Oldies, and even Adult Contemporary.
Lets take the voice of Ryan Seacrest who is a pop DJ at KIIS FM as well as American Idol host and E Network CoHost. Certainly people like his voice in the pop world. Is he more masculine than feminine, more feminine than masculine, or is he more androgynous in his communications / style.
He does have a similar voice to the ones I hear here in Hattiesburg on WNSL 100.3- SL100 (Pop music) and similar to the style of Seattle's KUBE 93.3 (Rhythmic Contemporary Hits) , KBKS-FM 106.1 (Contemporary Hits/Top-40) , and KNDD 107.7 (alternative) .
