I listen to both. I own tons of secular as well as christian artists. I went through a stage where after I got saved,I got rid of all my secular stuff & only listened to christian music...maybe for about 2 or 3 years. The more I grew & the more I prayed,etc...I just didn't feel it was a big issue anymore. Part of that was the fact I felt God told me to set aside all music & even playing my drums for a season,just because I think I was making music an idol in my life & it didn't matter to God if it was christian or secular,I was putting it before him. Once I had that time away,I came back with a much different attitude towards all music. Personally,I get a bit tired of people saying that this style or that style of music is or isn't of God or the devil. I hate when people give the devil credit for creating anything..he can't create. God made all music & it's up to man what we do with it,how we use it,interpret it...satan can only try to make a perverse copy of it.
