True and that's not really knocking their product. Range is overrated. Charlie Pride is a country legend and there's nothing rangy about his performances. The lead singer for the Cult is another guy who just makes a song work.It's not really that simple. The line between falsetto and head voice is quite blurred with male rock singers who have perfected this technique and that's why people are using terms like "super head voice" and "reinforced falsetto". Plant was the pioneer in this (well, until he ruined his voice somewhere between III and IV) and Steelheart's Miljenko Matijevic uses similar technique to hit the high notes (he goes to B5 in "Love Ain't Easy").
Quite off-topic, but definitely more interesting than EW's Voices of the Opera
