LOL. Josh Groban is a singer. He sings more of the operaish kind of songs like what Michael Buble sings (I think). Josh sings Italian music as well. One of his well-known songs (among many) is "I raise you up." (gets played on radio stations many many times) Sorry if my definition sucks, but here's the website. His music is awesome, imo.
