In myopinion, regardless of the sound system, a good song would always be a good song. Dont forget that the competetion is being judged not by the sound but by the content of the lyrics..The lyrics has to be from the Bible or be able to depict Bible based teachings..It doesnt matter what genre of music...it could be rap, reggae, rnb, pop, soft rock or heavy metal. Need I say the last group that won the price 2 yrs ago was a heavy metal band?
