20. AC/DC : Probably the best hard rock'n'roll bands to be exported out of Australia. A good song is Back in Black
18. Dio : Equal with Simon and Garfunkal. Only recently got into this band, but, they still are an excellent band with good singing, themes and guitaring. My favourite is Night People.
18. Simon and Garfunkel : The first of a few non-metal acts which I like. The excellent singing by the dynamic duo is why I like this band. A top song by them is Sound Of Silence.
17.Manilla Road : I really like this band. I don't know why. I just do. Necropolis is a freaking awesome song.
16.Blind Guardian : Blind Guardian are in my opinion one of the best epic power metal bands in the world with the song like Mirror Mirror.
15. Deep Purple : A pioneer of Rock, with THE most famous riff of all time in Smoke on the Water.
