The top three are easy choices, the last two i could fill with probably 100 others. I prefer female singers, but there doesn't seem to be as many. Irish women really rock my boat as well, thus Dolores at the top.
1. Ann Wilson from Heart (Powerful vocals with an impressive style.) 2. Amy Lee from Evanescence (A wide range of vocals from innocent to edgy.) 3. Hayley Williams from Paramore (A very melodic and easy-listening sound) 4. Stevie Nicks from Fleetwood Mac (An interesting style and range of vocal skills) 5. Janis Joplin from Big Brother & The Holding Company (Skilled and entirely underrated.)
