If quality was mesured by popularity, Britney Spears, Windows and McDonald would all be top quality in their respective category. Thanks god, it doesnt work like that.
Still, classical instrument arent present enough IMHO in popular composition. Great stuff can be made when you mix instruments and style, I just wish there was more people willing to try it out.
Who knows, maybe we will soon hear a duet of Eminem and an harpist (sp?)!
