Lead singer of the Cranberries. Besides having a funny name, ever-changing hair and strong opinions (ahem), she also happens to be an incredibly gifted melodist. Reached international fame at the age of 20. Seems to be less good now than she was then. This kind of things happen quite often (see Ronaldo).
Editor's note, January 15, 2018: Dolores O'Riordan died on this day at age 46.
