I think everyone has their own opinions about it, how they view Christian music.
As for me personally, I barely listen to secular music. Reason being, most secular songs have lyrics that are either: straight up depressing, about sex/unrequited love/breakups, or something ridiculously random. And I believe that lyrics are important when you're listening to a song. Most Christian music has very encouraging, edifying lyrics.
I agree that there is some Christian music that sounds ''secular'', and I think we all need to use wisdom & discernment when you're choosing who to listen to. Some of you might say to me ''It's just music", but it's not like that to me. Music is like words being spoken over your life, being spoken into your head over and over- with the accompanying melody. If you listen to the wrong words- it can mess with you, it can change your outlook, it can do a lot of things.
So yes, I do agree in some way with this thread- I don't really like some Christian music. I stay away from any that seem questionable. And then some of it I absolutely love. The songs that truly encourage & lift our spirit- they helped me with so much and there was even a song that led to my salvation.
