Yes amen. It'll cause ya pain, and you'll want to repent when you do those things.
I used to listen to country and even some of that Gaither mess (sorry but when I found out ole Gloria was a penny-cost-al preacher girl that did it for me) and tankfully when I got saved God tore me up over that. Chunked all them cd's and tapes...burnt em...stomped em...GLORY I feel like shouting all over again!
Sad thing is, if it's one of those old songs I knew before I was saved that I hear in the grocery store...I'll start humming. I hate that I didn't use my voice for God's glory then. I'll spend the rest of my time singing only the songs that HE should hear.
I got a cure for the "singing old worldy songs" problem though. Just burst into a verse of "Nothing But the Blood" or something like that....hehe it also clears the lines at the checkout too!
