Is All Christian Music Good?

I've been wondering about this topic for a while and would love to hear what everyone thinks. I've been listening almost exclusively to contemporary Christian music for the past 11 years (well, 90% of the time; I do love smooth jazz, too.) I just wonder about music produced by questionable ministries like Hillsong. They have some beautiful songs that really stir my soul and that I love for worship, but I wonder if there's any reason I shouldn't listen to them because of who produces them? It's obvious that not all music glorifies God or Jesus but when it comes to Christian music does it only matter what's in your heart? Anyone have any guidance? Many Blessings to you all!
