HELP!!! My college roomate is constantly playing Zakk Wylde songs. And when he's not doing boring repeptitive pentatonic shred, he's attempting to sing! He's been "singing" (aka butchering) "Heart of Gold" for three days now! And when I say butchering, I mean that when Neil Young sang this song, at least HE was on key! When my roomate sings it it's like a step and a half flat. How do I tell him that his voice is terrible?????? (Remember, I've gotta LIVE with this guy!)
