I'll go ahead and say it. Great art never(rarely) comes from music critics. We've all run into people(and have probably been that person at one time or another, I know I have) that loves to boldly proclaim the successes of their favorite artists and the failures and shortcomings of the ones who aren't worthy of their(often self-proclaimed) "golden ear". They will let you know their unsolicited opinion every time they see a post or tweet, hear a song or see a picture of the artist that happens to be the unfortunate victim of their "golden ear" and let you know that the only reason why _______ "made it" or "got signed" is because they were made into the artist that they are and actually, they aren't really an artist at all and have no talent. Often times said "music critic" will boldly proclaim in exaggerated terms and "verbage" his/her dislike of the artist and point to their "character" and lack of talent from a show that they went to or a video that they watched. "They suck", "that artist has no talent", "how in the world did they get a record deal?". The root of the issue is pride and often some type of insecurity and jealousy.
I've done it before and it's not right. We judge another artist's work and then go beyond what would be "acceptable criticism" and start launching into assaults on their character. For some reason, we like to forget Matthew 7:1-3 "Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you" I particularly like the KJV, it's quite poignant. "Judge not, that ye be not judged. For with what judgement ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again".
When it comes down to it, pride is at the root of most of our criticism. Often times it's because we feel insecure or are frustrated with another individuals success and frustrated with the lack of ours. We say that it's because no one else is standing up for what is obviously a travesty for the world's artistic sensibilities and that people need to hear what we have to say, when what it really comes down to is that we think we are better than others. It's pride. Proverbs 29:23 "One's pride will bring him low, but he who is lowly in spirit will obtain honor". Proverbs 26:12 "Do you see a man who is wise in his own eyes? There is more hope for a fool than for him" Galatians 6:3 "For if anyone thinks he is something, when he is nothing, he deceives himself"
At the end of the day we are nothing apart from Jesus Christ and his work on the cross. All of our criticisms of others are just vain attempts to elevate ourselves over others that we deem "less" or "undeserving" and ultimately we're creating idols out of our work, art, friends and creating enemies in our own minds out of people we should be giving grace to, regardless of what we think of their artistic contribution. Philippians 2:3 "Do nothing from rivalry or conceit, but in humility count others more significant than yourselves".
The opinions of self proclaimed "music critics", "art critics" or whoever is pounding you with constant negative opinions are often uninformed, biased and mired down in the "rightness" of what they think and feel and their experiences and they aren't usually willing to look at any other side but their own and the people that agree with them(which don't typically amount to very many).
It's easy to criticize and find fault with another person because people are flawed and sinful. Finding and pointing out the flaws in others is easy, pointing out the good, giving grace and loving others is not but it's what God calls us to do.
Be a creator and not a critic. If you constantly criticize, you'll never be able to create. No one really wants to hear what you have to say anyway......unless they ask.
