Lead singer of Creed, now gone solo. Love his deep voice, meaningful lyrics and the ability of his songs to powerfully believe in them. He can inspire a calm rebellion in the head.

Eddie Vedder:
Lead singer of Pearl Jam. The altern-god. Can you imagine "Jeremy", "Green Disease" without him? Recently got introduced to his song "Hard Sun". Love his song's lyrics and the rough yet velvety quality of the voice.

He ain't the Boss for nothing. There is something reassuring and comforting about his voice. Powerfully nostalgic, evoking deep-seated memories. He could be a vocal shaman.

Lead singer of Coldplay. Messiah of anemic rock. He has a mysteriously smooth vocal quality, not a baritone exactly but a versatile and pleasant voice.
